CI: Fail Numpy Dev build on DeprecationWarnings from numpy only
- [ ] [Tests added and passed](https://pandas.pydata.org/pandas-docs/dev/development/contributing_codebase.html#writing-tests) if fixing a bug or adding a new feature
- [x] All [code checks passed](https://pandas.pydata.org/pandas-docs/dev/development/contributing_codebase.html#pre-commit).

I believe the intent of `-W error` was to catch DeprecationWarnings from numpy primarily. Currently builds are failing because of a warning from distutils which idk if we can do anything about.
backport? > backport?

Yup probably a good idea @meeseeksdev backport 1.4.x
