PR Summary

This pull request adds preprocessing for the release title in the GitHub release action for the Besu project. Key changes include:

• Added a new "Pre-process Release Name" step in the artifacts job of the release.yml workflow
• Implemented a regex check to ensure the release name conforms to the valid Besu release format (YY.M.v[-suffix])
• Stores the validated release name as an environment variable for use in subsequent steps
• Enhances the release process by validating the release name format early in the workflow
