chore: update GitHub Actions workflow for AUTHORS file

- Added an explicit permissions block at the workflow level to define access for contents and pull-requests.
- Explicitly set the GITHUB_TOKEN in the checkout and create-pull-request steps for improved security and clarity.
- These changes enhance the maintainability and security of the workflow for updating the AUTHORS file.
