chore: enhance auto-tag workflow with version validation and error handling

- Added error handling for git fetch command to ensure workflow fails on tag fetch issues.
- Introduced a validation step to check the format of the new version tag, ensuring it adheres to semantic versioning.
- Updated the conditional execution for the release job to prevent running if no new tag is generated, improving workflow reliability.
