set stcal to main, allow python 3.13

[braingram]

Set stcal dependency to main and allow python 3.13 to allow the build sdist workflow (which appears to be picking up 3.13) to pass.

Fixes: #9110

Blocked by regtest failures: https://github.com/spacetelescope/RegressionTests/actions/runs/13037094545

This is also block by a TBD PR dropping 3.10 support since stcal main no longer support 3.10.

Tasks

• request a review from someone specific, to avoid making the maintainers review every PR
• add a build milestone, i.e. Build 11.3 (use the latest build if not sure)
• Does this PR change user-facing code / API? (if not, label with no-changelog-entry-needed)
  • write news fragment(s) in changes/: echo "changed something" > changes/<PR#>.<changetype>.rst (see below for change types)
  • update or add relevant tests
  • update relevant docstrings and / or docs/ page
  • start a regression test and include a link to the running job (click here for instructions)
    • Do truth files need to be updated ("okified")?
      • after the reviewer has approved these changes, run okify_regtests to update the truth files
• if a JIRA ticket exists, make sure it is resolved properly

I just started regtests on this old PR: #8864

Should I kill that off and start one with this?

Thanks for checking. I'd say leave them running. I expect failures which would be reason to not rush allowing 3.13.

[tapastro]

Perhaps worth adding an upper pin on 3.14 until we can test with it, once it exists? Opened #9110 to track reversion of #9106 - not sure if I did that in the proper git-wizard method but did my best.

[tapastro]

Would it be overloading the PR to also drop python 3.10 support here?

I'd say yes. Is there anything preventing dropping python 3.10? The python 3.13 bump requires further regtest investigation right?

Good idea on the upper pin! I'll add that to this PR.

The test set run on the closed PR ( https://github.com/spacetelescope/RegressionTests/actions/runs/13037094545 ) were fairly promising - perhaps worth investigating a possible change in numerical behavior for WFSS background subtraction, but the bulk differences look fairly innocuous to me.
