CI: Test pandas warnings as error on some builds
Locally I was validating the recent addition of `-W error:::pandas` and had to change it to `-W error:::$pandas` so validating if the CI will raise as well
So it appears the warning filter needs the fully qualified module name therefore we may need a way to generate all possible module paths in the library https://stackoverflow.com/a/73419829 Thx @mroeschke
