  Warning:  repo `https://github.com/pre-commit/pre-commit-hooks` uses deprecated stage names (commit, push) which will be removed in a future version.  Hint: often `pre-commit autoupdate --repo https://github.com/pre-commit/pre-commit-hooks` will fix this.  if it does not -- consider reporting an issue to that repo.
