   • Remove unused clang-format install
   • Remove workaround after bumping to jammy
   • Use a PPA to pin the python version instead of having to pick from the limited system-packaged python versions
2. Remove clang-format from lint task

   This was added to use clang-format in scripted diffs, but remained
   largely unused.

   CI fails 🤷‍♂️

   Looks like that’s because:

   0- Ubuntu 20.04 (focal) Python3.5 - Python3.7, Python3.9 - Python3.11
   1- Ubuntu 22.04 (jammy) Python3.7 - Python3.9, Python3.11
   

   If you apt-get install -y python3.7-venv it works.
