Add CI for tests

[mawad-amd]

Add CI for testing using Apptainer images. The tests are running one at a time because pytest is not so friendly with MPI and ends up stuck.

Why apptainer and not docker:

Ideally, we want both workflows but long story short, docker is problematic on the host node because we end up using the VFS storage instead of overlay2 and with VFS we end up with 1.6 terabytes of artifacts that we can’t get rid of.

• Running MPI as root poses security risks and is generally discouraged. Consider creating a non-root user in the container or using proper privilege escalation mechanisms instead of --allow-run-as-root.
