This is trying to fix the current failures on main.
It seems that our test runs were still using numpy 1.26 (because of some downgrade after initial env creation because of removing nomkl), but that stopped being the case some hours ago. This turns up a bunch of failures in our tests when running hem with numpy >= 2 ánd with
NPY_PROMOTION_STATE=legacy
.We should properly fix this situation (stop using the legacy promotion state), but this PR should already get CI green again.
