chore: sign Version Packages automation commits

[alexz-phantom]

Summary

• switch the Changesets automation from Git CLI commits to the GitHub API
• ensure generated Version Packages commits and tags are GPG-signed by GitHub

Validation

• actionlint -ignore 'setup-node@v3' .github/workflows/release.yml
• git diff --check

The ignored setup-node@v3 actionlint finding predates this change.

Summary by CodeRabbit

• Chores
  • Improved the release process by updating how release changes are committed.
