Rebased to include https://github.com/spacetelescope/stcal/pull/303 to test it with python 3.13

Converted this back to draft. The build with 3.13 failed due to failure to build a wheel for scikit-image: https://github.com/spacetelescope/stcal/actions/runs/11278541799/job/31367250216?pr=300#step:7:997 It looks like they don't have a 3.13 release yet: https://pypi.org/project/scikit-image/#files I don't think was previously failing so I'll try to re-run the job but it probably makes sense to wait until they have a release with 3.13 wheels.

scikit-image, added support in scikit-image/scikit-image#7565 and wheels as part of scikit-image/scikit-image#7571, both of which have appeared in version 0.25.0rc1. That pre-release version includes Python 3.13 wheels, so I have temporarily forced the installation of the pre-release when using 3.13. According to https://github.com/scikit-image/scikit-image/issues/7596#issuecomment-2440286571 the release 0.25 will have support for Python 3.13 and seems like it should occur soon.

If we are comfortable using the pre-release for now (I believe it will pull the release once that comes out), I think this PR is ready.
