unexpected mypy error in matplotlib functions in plotting

[dkrako]

Current Behavior

mypy fails since today. It has to do something with matplotlib type definitions, maybe there was an update?

Expected Behavior

There should be no new mypy errors on this untouched code.

Minimum acceptance criteria

• [ ] get rid of this error

Steps to Reproduce

rm -rf .tox/mypy  # clean mypy environment
tox -e mypy

I'll fix it, interestingly pre-commit.ci does not fail

I found the root cause:

https://github.com/matplotlib/matplotlib/releases

matplotlib 3.8 was released which got rid of typestubs and now uses inherent typing (which is different), I'll fix it asap.
