Fix release workflow uploading .gitignore as asset

The `dist/*` glob pattern matched the `.gitignore` file in the dist/
directory, which GitHub API renamed to `default.gitignore` when
uploading as a release asset. Use explicit file patterns (*.whl and
*.tar.gz) to only upload actual build artifacts.
