EKAT is failing to install cacts in CI with

ERROR: Could not install packages due to an OSError: [Errno 13] Permission denied: '/projects/e3sm/software/eamxx-venv/lib/python3.11/site-packages/cacts'
Check the permissions.

I can't be 100% sure this will fix our EKAT CI, since I need to get the PR merged, and rebuild our CI image first, but I'm quite confident (and I have a friend backing me up).

Looks good, btw, feel free to add tests for downstream stuff here (like EKAT) much like we do for e3sm-case, etc.

We would have to test running something as a different user, and verify all tools are ok. E.g., verify we can install stuff in the venv. If I have time, I'll do it.
