Fix docs deploy auth in Publish Documentation workflow

[Copilot]

Build-Deploy-Documentation failed in Publish Documentation because the deploy step could not authenticate git push to gh-pages. This updates the workflow to use GitHub-native credentials/permissions for Docusaurus deployment.

• Root cause addressed

  • Deploy step relied on custom Git credentials (GIT_USER/GIT_USER_TOKEN) that were rejected during git push.

• Workflow auth + permission changes

  • Added workflow-level contents: write permission.
  • Switched deploy credentials to ${{ secrets.GITHUB_TOKEN }} with x-access-token username.
  • Set deploy commit identity to github-actions[bot] noreply email.

• File updated

  • .github/workflows/publish-docs.yml

permissions:
  contents: write

env:
  GIT_USER: x-access-token
  GIT_PASS: ${{ secrets.GITHUB_TOKEN }}

run: |
  git config --global user.name "github-actions[bot]"
  git config --global user.email "41898282+github-actions[bot]@users.noreply.github.com"
  npm run deploy
