Use gh CLI for release creation

Replace GitHub Action with gh CLI:
- Use 'gh release create' which handles both tag and release
- Generate formatted release notes with changes, download, requirements
- gh CLI might have better permission handling than third-party actions
- Uses GH_TOKEN environment variable

This should work with default GitHub Actions permissions.
