Source release PAT from publishing environment and drop unused smoke-test token refs

[Copilot]

Aligns the release automation workflows with the established push workflows by sourcing the release PAT from the admin-restricted publishing environment instead of repository-level secrets, renames it to RELEASE_AUTOMATION_PAT, and removes dead GITHUB_TOKEN references that the smoke-test action never consumes.

Changes

• release-pr.yml: Added environment: publishing to the update_manifest_files job so the PAT resolves from the publishing environment (matching version-history.yml and the push workflows). Renamed secrets.PAT → secrets.RELEASE_AUTOMATION_PAT in both push and PR-creation steps.
• version-history.yml: Renamed secrets.PAT → secrets.RELEASE_AUTOMATION_PAT (job already runs in environment: publishing).
• Smoke workflows (smoke-*.yaml): Removed the unused env: GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }} blocks (15 occurrences across 14 files). The smoke-test composite action and its scripts never reference GITHUB_TOKEN, and several smoke workflows (cpp, jekyll, base-alpine) already omitted it.

The push workflows authenticate to the registry via TOKEN_NAME/PASSWORD and were left unchanged.

  update_manifest_files:
    runs-on: ubuntu-latest
    environment: publishing        # secrets resolve from the admin-only env
    ...
      - name: Push manifest updates
        env:
          GITHUB_TOKEN: ${{ secrets.RELEASE_AUTOMATION_PAT }}

Follow-up

Requires the PAT secret in the publishing environment to be renamed to RELEASE_AUTOMATION_PAT for these workflows to function.

Pull request overview

Updates GitHub Actions workflows to use a publishing-environment PAT for release automation (instead of a repo-level PAT secret), and removes unused GITHUB_TOKEN environment wiring from smoke workflows to reduce confusion and unnecessary secret exposure.

Changes:

• Switch release automation workflows from secrets.PAT to secrets.RELEASE_AUTOMATION_PAT and align release-pr.yml with other publishing-environment workflows by adding environment: publishing.
• Remove unused env: GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }} blocks from multiple smoke workflows.
• Update the smoke-test composite action to use actions/checkout@v6.
