Pre-commit autoupdate

Description

I noticed that pyupgrade was using py-37 style which I updated to py-38 and pre-commit autoupdate more generally which causes a number of automated changes

I don't understand where the error comes from. It looks like assert isinstance(env, gym.Env) doesn't exclude that env can be a string or None.

Moreover, the syntax a: Type1 | Type2 requires Python >=3.10, isn't it? Because we are currently supporting >=3.8

I believe we can add from __future__ import annotation to fix that issue
