  Fix Arch Linux tests
  The Arch Linux tests are failing due to new versions of pip needing to use the `--break-system-packages` flag to install packages globally. We should update the CI to use a virtualenv here.
  CI: try to bring back Arch Linux CI
  Let's see if this works now with virtualenv setup
