Better way to run slow linters in CI only

• update pre-commit hooks
• a better implementation of Improve local pre-commit experience #9333, taking advantage of pre-commit manual hook stages

Sooo... what part of the universe changed so we suddenly have tests failing with No module named easy_install ?

[pradyunsg]

pypa/setuptools#2544 -- setuptools got rid of easy_install! \o/

[sbidoul]

Good. So I guess we can stop testing that we correctly uninstall stuff installed with easy_install ?

[uranusjr]

I think we still should test against easy_install since there are still all those Ubuntus shipping them. I’ve filed #9509 to fix this.

I was going to ask, does this change mean I can run tox -e lint -- mypy without errors again?

I was not aware of that issue, but yes, it does :)
