CI: precommit

[Borda]

Add pre-commit which would is defined already and the auto-black does not work for fork PRs Also, I would suggest enabling this bot - https://pre-commit.ci/ which would push fixes for any/all PRs

@vturrisi mind checking this suggestion and approving CI? :otter:

I'm not really knowledged about pre-commit, but LGTM as it doesn't break anything.
