Show deprecation warnings in doc build? #23866
Description
Problem
#23862 fix a deprecation warning that was triggered by an untested bit of code. However, that code is executed in the documentation build.
Proposed solution
It may make sense to at least let the documentation build show deprecation warnings. It should maybe not error on them, although it somehow would make sense to error on Matplotlib deprecation warnings.
