Stabilize Copilot review setup for MkDocs installs and builds

[Copilot]

Copilot code review setup was failing in the Install MkDocs and extensions step, which prevented review runs from initializing reliably. This change makes the setup workflow independent of implicit working-directory behavior and avoids blocking on unrelated pre-existing MkDocs warnings.

• Setup path resolution

  • Remove the job-level working-directory override from the Copilot setup workflow.
  • Use explicit repo-root paths for both dependency installation and MkDocs config loading.

• MkDocs verification behavior

  • Change the setup-time MkDocs verification from strict mode to a normal build so existing documentation warnings do not fail Copilot review initialization.

• Resulting workflow shape

  - name: Install MkDocs and extensions
    run: pip install -r .github/requirements.txt
  
  - name: Verify MkDocs build
    run: mkdocs build -f .github/mkdocs.yml

• Fixes One or more custom setup steps configured for this repository failed during this Copilot code review run: #312

Pull request overview

This PR updates the GitHub Actions workflow used for Copilot review setup steps to make MkDocs dependency installation and build verification more reliable by removing reliance on an implicit working directory and by avoiding strict build failures.

Changes:

• Removed the job-level defaults.run.working-directory override.
• Updated MkDocs dependency installation to use an explicit repo-root path (.github/requirements.txt).
• Updated the MkDocs verification step to run a normal build using an explicit config file path (-f .github/mkdocs.yml) instead of --strict.

Implemented in commit 8e1812e by setting the Verify MkDocs step to run in ./.github and using mkdocs build -f mkdocs.yml so the config’s relative paths resolve deterministically.

One or more custom setup steps configured for this repository failed during this Copilot code review run:

Install MkDocs and extensions

Setup steps run before each review. If the review above is missing context, or no review was posted at all, the failing step above may be the cause. See the workflow run for failure details, fix your setup steps configuration, and re-request a review.

Note

You can configure setup steps for Copilot code review separately from Copilot cloud agent with a copilot-code-review.yml file. Read the docs for details.
