refactor: enhance GitHub Actions workflow to resolve version tags

- Updated the Arch news watcher workflow to include a function for resolving the current version tag from the GitHub API.
- Replaced direct API calls with a more structured approach to handle version retrieval, improving maintainability and error handling.
- Adjusted the logic for determining the minimum version based on the resolved version.
