TYP: Mypy failures with new numpy

[phofl]

Mypy raises a lot of errors since the new numpy is available on conda-forge. What is the best approach here? Adding ignores for everything and fixing them step by step afterwards?

#36092 is basically doing that (needs an update)

in the short term we should just pin numpy on ci and checks while we discuss.

another option could be remove any problematic type annotations from type signature, return types or variable annotations, they are likely incorrect in some cases which is why mypy is reporting errors

#39526 has been backported to get ci green on 1.2.x but that PR changes environment.yaml.

I don't think we want to release with that change, so labelled as blocker for now.
