🐛 Fix usage test to Ubuntu 22.04

Problem:
- `ubuntu-latest` will be `ubuntu-24.04` imminently, and that version doesn't
  handle pip in the same way.

Solution:
- Pin usage test to `ubuntu-22.04`.

Note:
- When we update to `ubuntu-24.04` for real, we'll probably want to use pipx. We
  may also need to separate unit test workflows to support older compilers.
