🚀 Enhance Auto PR action with improved metadata and error handling

This commit brings significant improvements to our Auto PR action:

🔧 Updated action metadata:
- Renamed action to "Auto PR: dev to main/master" for clarity
- Improved description to better reflect the action's functionality
- Updated author information

✨ Enhanced PR creation logic:
- Added a check to compare commits between base and head branches
- Implemented graceful handling when there are no commits to create a PR for

These changes will make the action more robust and informative, reducing potential errors and improving overall user experience. The new commit comparison feature ensures we only create PRs when there are actual changes to review, streamlining our development workflow.
