many CI failures related to pkg_resources #11476

DeprecationWarning: Implementing implicit namespace packages (as specified in PEP 420) is preferred to
pkg_resources.declare_namespace. See https://setuptools.pypa.io/en/latest/references/keywords.html#keyword-namespace-packages
it happens on the line import pkg_resources. Here's a full traceback for the pybtex case:
