Nick Vigilante c84aa564ba docs: normalize code-fence languages for Shiki compatibility (#27161)
Normalizes non-standard code-fence language tags across `docs/**` so a
strict highlighter (Shiki, used by Fumadocs) won't fail the build on an
unrecognized language, and unifies redundant synonym tags onto one
canonical form per language. The current renderer (Speed-Highlight)
detects the language from the code content, not the fence label, so this
drift wasn't visible until now.

## Changes

- `hcl` -> `tf` (199 fences, including indented ones nested in
numbered/bulleted lists). Shiki ships `hcl` and `terraform` as two
distinct grammars (not aliases); every `hcl`-tagged fence in `docs/**`
is actually Terraform resource/data/provider syntax, so the more
specific `terraform` grammar is correct for all of them. `tf` is Shiki's
own alias for that grammar, and it's also what GitHub's own markdown
renderer resolves to the same HCL/Terraform highlighting.
- `pwsh`/`powershell` -> `ps1`. Both `ps` and `ps1` are registered
PowerShell aliases in Shiki, but on GitHub's renderer only `.ps1` is a
registered file extension (`.ps` isn't), so `ps1` renders identically to
`powershell` there today while bare `ps` would silently lose
highlighting.
- `env` -> `dotenv` (a dedicated Shiki grammar for `KEY=VALUE` files)
- `text`/`output`/`none`/`url` -> `txt`. Same built-in plain-text
fallback either way, just shorter.
- `Dockerfile` -> `dockerfile` (lowercase)
- `bash`/`shell` -> `sh` (732 fences). Shiki and GitHub both alias all
three to a single shell grammar; this was already the style guide's
stated preference, just not enforced across the existing corpus until
now.
- `markdown` -> `md` (4 fences). Alias of the same grammar in both Shiki
and GitHub.
- `jsonc` -> `json` (1 fence). The block has no comments or trailing
commas, so it doesn't need the comments-capable grammar.
- `ts` -> `tsx` (2 fences, `docs/about/contributing/frontend.md`).
Verified the actual content tokenizes identically under both grammars,
and a sibling block in the same file already needs `tsx` for real JSX,
so unifying to one tag is safe for this file. Documented a caveat: `tsx`
mis-tokenizes the legacy angle-bracket type-assertion syntax
(`<Type>value`), which is invalid in real `.tsx` files anyway, so use
`value as Type` instead.
- `yml` -> `yaml` (1 fence)
- Updated `docs/.style/style-guide/formatting.md` to document all
canonical tags

`promql` (2 fences) and `caddyfile` (2 fences) are left as-is. Shiki
doesn't bundle a grammar for either, so they need a custom grammar
registration when the site adopts Shiki, rather than degrading to `txt`.
Tracked as follow-up work under DOCS-118 and
[DOCS-544](https://linear.app/codercom/issue/DOCS-544/vendor-a-local-promql-grammar-for-shiki-syntax-highlighting)
(promql).

Does not touch `offlinedocs/`.

<details>
<summary>How the fence tags were verified</summary>

Each tag was tested against a real `shiki@latest` highlighter instance
(`codeToHtml`/`codeToTokens`) and cross-checked against GitHub's
`@wooorm/starry-night` grammar sources (the renderer that actually
displays these `.md` files today, in repo browsing and PR diffs), since
that's what determines whether brevity is safe before Shiki adoption:

```text
FAIL  env        -- Language `env` is not included in this bundle.
FAIL  Dockerfile -- Language `Dockerfile` is not included in this bundle.
FAIL  promql     -- Language `promql` is not included in this bundle.
FAIL  caddyfile  -- Language `caddyfile` is not included in this bundle.
FAIL  pwsh       -- Language `pwsh` is not included in this bundle.
FAIL  output     -- Language `output` is not included in this bundle.
```

`hcl` doesn't error in Shiki, since it's a real grammar, but that's
exactly the trap: it was silently rendering every fence with the generic
HCL grammar instead of the Terraform-specific one. Every `hcl`-tagged
fence in `docs/**` was manually checked against `origin/main` and is
genuinely Terraform content.

For `ts`/`tsx`, tokenizing the actual doc content confirmed identical
output under both grammars; a synthetic test with the legacy
angle-bracket cast syntax confirmed `tsx` degrades on that specific
construct, which the style guide now calls out.

The first normalization pass only matched fence tags at column 0
(`^```tag$`), missing tags indented inside numbered/bulleted lists. A
follow-up pass caught the remaining occurrences at any indentation
level.

# Installing Coder
A single CLI (`coder`) is used for both the Coder server and the client.
We support two release channels: mainline and stable - read the
[Releases](./releases/index.md) page to learn more about which best suits your team.
There are several ways to install Coder. Follow the steps on this page for a
minimal installation of Coder, or for a step-by-step guide on how to install and
configure your first Coder deployment, follow the
[quickstart guide](../get-started/index.md).
> [!TIP]
> If you're installing Coder for the first time, the [Quickstart](../get-started/index.md) guides you through installing Coder and launching your first workspace.
## Local/Individual Installs
This install guide is meant for **individual developers, small teams, and/or open source community members** setting up Coder locally or on a single server. It covers the light weight install for Linux, macOS, and Windows.
<div class="tabs">
## Linux/macOS
Our install script is the fastest way to install Coder on Linux/macOS:
```sh
curl -L https://coder.com/install.sh | sh
```
Refer to [GitHub releases](https://github.com/coder/coder/releases) for
alternate installation methods (e.g. standalone binaries, system packages).
## Windows
If you plan to use the built-in PostgreSQL database, ensure that the
[Visual C++ Runtime](https://learn.microsoft.com/en-US/cpp/windows/latest-supported-vc-redist#latest-microsoft-visual-c-redistributable-version)
is installed.
Use [GitHub releases](https://github.com/coder/coder/releases) to download the
Windows installer (`.msi`) or standalone binary (`.exe`).
![Windows setup wizard](../images/install/windows-installer.png)
Alternatively, you can use the
[`winget`](https://learn.microsoft.com/en-us/windows/package-manager/winget/#use-winget)
package manager to install Coder:
```ps1
winget install Coder.Coder
```
</div>
## Hosted/Enterprise Installs
This install guide is meant for **IT Administrators, DevOps, and Platform Teams** deploying Coder for an organization. It covers production-grade, multi-user installs on Kubernetes and other hosted platforms.

## Starting the Coder Server
To start the Coder server:
```sh
coder server
```
![Coder install](../images/screenshots/welcome-create-admin-user.png)
To log in to an existing Coder deployment:
```sh
coder login https://coder.example.com
