Review/reconsider PC140 precommit + mypy

[Carreau]

I'm in the process of removing/forbiding the run of mypy via pre-commit/hatch on jupyter_client and likely other places as running via pre-commit/hach can (often?) swallow error.

try to clone jupyter client main, currently 0bce36fb216d228d755f6c1ca3473cfb4e0f29a6, and run:

$ hatch run typing:test # noerror

$ pre-commit run --all-files --hook-stage manual mypy  #no error

$ mypy  # this works and detect **real** issues.

My guess is pre-commit/hatch create envs just to run those tools, and if something goes wrong and mypy run in those envs, it may find the wrong version of your package.
