Fix release pipeline and bump GitHub Actions to Node 24 runtimes (#14)

- Pass explicit tag_name to action-gh-release so release assets attach
  correctly instead of failing with "GitHub Releases requires a tag"
- Bump checkout (v4->v7), setup-dotnet (v4->v5), upload-artifact (v4->v7),
  and action-gh-release (v2->v3) to clear the Node 20 deprecation warning
