Fix npm workflow to handle existing tags and releases gracefully

- Add check for existing GitHub releases before creating new ones
- Allow Docker builds to proceed even if tag exists
- Skip tag creation if it already exists
- Update existing release with Docker information if release exists
- Only fail on existing tags if Docker is not enabled
- Use gh CLI to check and update releases
