* Update pre-commit hooks:
- github.com/psf/black: 21.5b1 → 21.6b0
- github.com/asottile/pyupgrade: v2.15.0 → v2.20.0
* Revise pre-commit hook order given linear execution
- pre-commit hooks execute in order of definition in .pre-commit-config.yaml, so hooks that can change the codebase should execute before linter hooks
