Bug 2350302

python-readme-renderer fails to build with python-pygments 2.19.1 in Fedora 43.
I intend to update python-pygments in Fedora Rawhide in ~1 week.

There may be an upstream solution to the issue (not tested), see:
https://github.com/pypa/readme_renderer/commit/04d5cfe76850192364eff344be7fe27730af8484 

The failure:
