Black formatting on github fails.

On my machine:

$ black -S --check keepassxc_browser setup.py example.py
All done! ✨ 🍰 ✨
7 files would be left unchanged.

with black, 22.1.0

Probably because an older version is used in CI:

python-keepassxc-browser/dev-requirements.txt

Line 1 in a06cb38

black==19.10b0

I guess failures will be gone after changing that line to black==22.1.0
