Set github runner to ubuntu-22.04 (#80)

ubuntu-latest (24.04) has newer version of pip which blocks
installing packages outside of a venv, which our actions and some
 upstream actions we use rely on.

Quickest to roll back the runner version for the short-term until
the upstream actions are patched.
