Jim 1fbd029754 fix(provisioner/terraform): sync version constants with the shipped binary (#27871)
`provisioner/terraform/install.go` still pins `TerraformVersion` to
1.14.5 and `maxTerraformVersion` to 1.14.9, but the shipped binary has
been Terraform 1.15.5 since v2.35.0. `scripts/Dockerfile.base`,
`install.sh`, `mise.toml`, `mise.lock`, and `flake.nix` all track
1.15.5; only the Go constants were left behind, which makes the `NOTE:
Keep this in sync with ...` comments on those constants false.

Two user-visible effects on the same release:

- Provisioner daemons that have a system Terraform log `installed
terraform version newer than expected, you may experience bugs
installed_version=1.15.5 max_version=1.14.9` on every startup. The check
at
[`provisioner/terraform/serve.go#L122-L126`](https://github.com/coder/coder/blob/79723db2d23b6b941e405a8d3c2200206e7e4cb4/provisioner/terraform/serve.go#L122-L126)
is warn-only, so the 1.15.5 binary is used anyway and the warning is
pure noise.
- Hosts *without* a system Terraform fall through to `Install()` at
[`serve.go#L105`](https://github.com/coder/coder/blob/79723db2d23b6b941e405a8d3c2200206e7e4cb4/provisioner/terraform/serve.go#L105),
which downloads `TerraformVersion`. So the same Coder version provisions
with 1.15.5 in some environments and 1.14.5 in others.

This sets `TerraformVersion` to 1.15.5 and `maxTerraformVersion` to
1.15.9, keeping the existing `.9` convention that auto-allows patch
releases. `minTerraformVersion` is unchanged. No other file needed
updating; everything else already tracks 1.15.5.

This is a consistency fix, not a CVE remediation.

The divergence was already identified as [CRF-2 in the review of
#27183](https://github.com/coder/coder/pull/27183#pullrequestreview-4685322854)
(`provisioner/terraform/install.go:25`), which noted that leaving the
constants behind means "a maintainer who trusts it could 'resync'
install.sh/Dockerfile.base back to 1.14.5". That PR was closed for
unrelated reasons; this change addresses only the drift.
