tests failing when resources unavailable after building from Github tarball

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 using `installer` module
- run pytest with $PYTHONPATH pointing to sitearch and sitelib inside
- 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:

```console
+ PYTHONPATH=/home/tkloczko/rpmbuild/BUILDROOT/python-cssutils-2.11.0-2.fc37.x86_64/usr/lib64/python3.10/site-packages:/home/tkloczko/rpmbuild/BUILDROOT/python-cssutils-2.11.0-2.fc37.x86_64/usr/lib/python3.10/site-packages
+ /usr/bin/pytest -ra -m 'not network'

Please let me know if you need more details or want me to perform some diagnostics.

Start with cssutils/tests/test_cssutils.py and cssutils/tests/test_scripts_csscombine.py, then reproduce the failures using pytest -m 'not network' in the installed tarball environment. Trace how these tests locate their resources and compare that with the PEP517 build, wheel installation, and PYTHONPATH setup. Done means the non-network test run no longer fails when built from a GitHub tarball.
