Include system updates in CI

We need this because sometimes `ubuntu-latest` is a slightly older version of ubuntu which crashes because it doesn't know what `--break-system-packages` means, and at other times `ubuntu-latest` is a slightly newer version of ubuntu which requires `--break-system-packages` to pip install anything.

Forcing system updates will *HOPEFULLY* update to the newest python which knows and requires this flag.
