Continuous Integration test is failing due to missing libmkl_rt.so.2

Continuous integration tests are failing due to some error with the mkl lib. I suspect it may be related to upgrading artifacts actions from v3 to v4 based on the timing? #674

Here's an example failed run:

I ran into the same error with libmkl when trying to help a new undergrad student install RMG yesterday, so I don't think it's just a database problem.

CI tests are now passing due to ReactionMechanismGenerator/RMG-Py#2766
