test_no_user_warning assumes pip is available

[kloczek]

I'm packaging your module as an rpm package so I'm using the typical PEP517 based build, install and test cycle used on building packages from non-root account.

• python3 -sBm build -w --no-isolation
• because I'm calling build with --no-isolation I'm using during all processes only locally installed modules
• install .whl file in </install/prefix> using installer module
• run pytest with $PYTHONPATH pointing to sitearch and sitelib inside </install/prefix>
• build is performed in env which is cut off from access to the public network (pytest is executed with -m "not network")

Here is pytest output:

+ PYTHONPATH=/home/tkloczko/rpmbuild/BUILDROOT/python-astroid-3.1.0-2.fc36.x86_64/usr/lib64/python3.9/site-packages:/home/tkloczko/rpmbuild/BUILDROOT/python-astroid-3.1.0-2.fc36.x86_64/usr/lib/python3.9/site-packages
+ /usr/bin/pytest -ra -m 'not network'
