docs: clarify dev containers entry point and reduce callouts (#21188)

The user guide jumped straight into integration details without explaining
what dev containers are. Now it opens with a brief orientation linking to
the spec, then explains this guide covers the Docker-based approach.

Converted several NOTE callouts to prose where they were just cross-references
or stacked unnecessarily. The Envbuilder index note was reframed to lead with
its strengths rather than "we recommend the other thing."

Also updates platform support to Linux only per current status.

# Configure a template for Dev Containers

This guide covers the Dev Containers Integration, which uses Docker. For
environments without Docker, see [Envbuilder](./envbuilder/index.md) as an
alternative.
To enable Dev Containers in workspaces, configure your template with the Dev Containers
modules and configurations outlined in this doc.

> Dev Containers require a **Linux or macOS workspace**. Windows is not supported.
Dev Containers are currently not supported in Windows or macOS workspaces.

The `workspace_folder` attribute must point to a valid project folder containing
a `devcontainer.json` file. Consider using the
[`git-clone`](https://registry.coder.com/modules/git-clone) module to ensure
your repository is cloned and ready for automatic startup.
For multi-repo workspaces, define multiple `coder_devcontainer` resources, each
pointing to a different repository. Each one runs as a separate sub-agent with
