TEST: Revert "pin numpy<2 (#8565)"

[braingram]

TEST PR

As noted https://github.com/spacetelescope/stcal/pull/266#issuecomment-2176314536 the next release will keep the <2 numpy pin. This PR is to test what other issues will need to be addressed to eventually remove this pin.

This reverts commit 380dc5eb082c6c5d4e024a9337999f69cd5b8443, reversing changes made to a0cdad8b9ce9b9e3835bb1893ace205f40623798.

Known issues are:

• scikit-image numpy 2.0 incompatibility
• stsci.imagestats upper pin (addressed in https://github.com/spacetelescope/jwst/pull/8577)
• test_coron failures (again because of image matching, https://github.com/spacetelescope/jwst/issues/8579)
• refpix type promotion issues https://github.com/spacetelescope/jwst/issues/8578
