Current master branch build fails, see https://dev.azure.com/sloria/sloria/_build/results?buildId=12400&view=logs&j=ea246cef-d1aa-57f5-7a3e-96f81afd1e8b&t=dbea0cb8-2fce-5953-3cb5-dc5f7d114bd9&l=43

Traceback (most recent call last):

ImportError: cannot import name '_unicodefun' from 'click' (/home/vsts/.cache/pre-commit/repo5cfip9ka/py_env-python3/lib/python3.10/site-packages/click/__init__.py)

This just requires a black update, see psf/black#2964

@sloria This should be a quick and easy review 🙂
I want to clean the CI on master before moving on to another PR.
