Related issues

• Fixes STU-1384

Proposed Changes

• Changes the GitHub release display name from v1.7.5 to Version 1.7.5 for a more human-readable format
• The git tag remains unchanged as v1.7.5
• Updates both create_draft_github_release and publish_release lane to use the new name format
• After the release-toolkit creates the draft with the tag-based name, an Octokit API call renames it to the Version X.Y.Z format

Testing Instructions

1. Review the diff in fastlane/Fastfile
2. Verify the create_draft_github_release method now sets release_name = "Version #{version}" and updates the draft release name via the GitHub API
3. Verify the publish_release lane now looks for the draft by "Version #{version}" instead of "v#{version}"

Pre-merge Checklist

• Have you checked for TypeScript, React or other console errors? (Tests pass, no errors)

Closing in favor of #2728. We decided to move this change to the release-toolkit.
