Update pre-commit black and isort version

This would solve the failed github action

See:

• https://github.com/PyCQA/isort/issues/2077

It seems that #167 needs to be merged first.

It’s failing on what seems like installation failure for isort, maybe include that commit in your PR to run them both in one go here?

Python reminds me of JavaScript a lot lately…

Updated @dfunckt :rocket:

OK, checks pass -- I'll merge this one to unblock CI and we can bump pypy and action versions separately.

Thanks @hashlash and @cclauss !
