CI: Builds failing in ``pandas.show_versions()``

Failing on all platofrms. E.g. https://github.com/pandas-dev/pandas/runs/4581277621

Probably fine to just remove pip from the list of packages to print the version of then?

60.0.3 did not fix all problems for us unfortunately. When running this locally I get

Traceback (most recent call last):

It looks like it tries to distutils from stdlib, but if running

import importlib
importlib.import_module("setuptools")

it is pulling the distutils from

'/tmp/testenv2/lib/python3.10/site-packages/setuptools/_distutils'

Not sure what is different when doing this via pandas.show_versions()
