Our CI run with pre-release dependencies currently fail: https://github.com/quaquel/EMAworkbench/actions/runs/9154380335/job/25164846180

Which is caused by an update in NumPy 2.0 - which is currently in release-candidate phase.

FAILED test/test_analysis/test_prim.py::PrimBoxTestCase::test_inspect - AttributeError: `np.NaN` was removed in the NumPy 2.0 release. Use `np.nan` instead.. Did you mean: 'nan'?

Looks like a simple case, will look into it soon. We probably want to backport this.
