Pull request overview

Updates the Release GitHub Actions workflow so it can correctly draft releases when PRs from hotfix-* branches are merged into main, not just release-* branches.

Changes:

• Derive the release version from either release-x.y.z or hotfix-x.y.z branch names.
• Add explicit validation and actionable error messages when the branch naming/version format is invalid.
