Suppress numpy warnings in python implementation of Elemwise

[ricardoV94]

Closes #1577

We don't warn in any of our other backends, so it doesn't make sense to warn when using Python. This is specially annoying because we constant-fold with Python but didn't use to. This led to failures in the pymc-extras CI: pymc-devs/pymc-extras#597

Failing test is the known unrelated bad boy

Failing test is the known unrelated bad boy

I thought the previous failures were due to numpy < 2 but I guess it's a float32 thing now. Anyway not related to this PR so I don't care. Re-triggered the run to get a green dot, but feel free to not wait.

I don't understand that test, there's not even anything stochastic in it. Can't be bothered to debug rn
