0.8.2: pytest is failing in `test/test_contrib/test_github_wiki.py::TestGithubWiki::test_parse` unit and `DeprecationWarning` warnings

I’m trying to package 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>
• run pytest with PYTHONPATH pointing to sitearch and sitelib inside </install/prefix>

Here is pytest output:

+ PYTHONPATH=/home/tkloczko/rpmbuild/BUILDROOT/python-mistletoe-0.8.2-2.fc35.x86_64/usr/lib64/python3.8/site-packages:/home/tkloczko/rpmbuild/BUILDROOT/python-mistletoe-0.8.2-2.fc35.x86_64/usr/lib/python3.8/site-packages
