Disable pre-commit.ci autofixes

The automagically pushed commits make non-squash merges impossible :/

I'd rather use squash merges (also produces a nicer git history) and get the benefit of pre-commit.ci autofix. But I can live without if you feel stronger about it @akx

@valberg I prefer having the choice 😁 Sometimes well-built branch histories with a regular merge commit can be their worth in gold (e.g. when git bisecting or git blameing).
