add class aliases for steps

[braingram]

As discussed in spacetelescope/roman_datamodels#343 stpipe expects the class_alias of a step to match the meta.cal_step.<class_alias> attribute assigned when a step is skipped.
https://github.com/spacetelescope/stpipe/blob/677f6a43b7c101f490a5d923a653d20c7fbe493b/src/stpipe/step.py#L485

This PR updates all steps in romancal to have a class_alias that matches the string used in the l2_cal_step schema:
https://github.com/spacetelescope/rad/blob/main/src/rad/resources/schemas/l2_cal_step-1.0.0.yaml

Regression tests all pass: https://github.com/spacetelescope/RegressionTests/actions/runs/11801390936

Tasks

• request a review from someone specific, to avoid making the maintainers review every PR
• add a build milestone, i.e. 24Q4_B15 (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

Great. Thanks Brett. Can you remind me if this has regression test impacts? I agree it's good to have the class aliases.

Great. Thanks Brett. Can you remind me if this has regression test impacts? I agree it's good to have the class aliases.

I expect this won't change regression tests (yet). There is still an issue where stpipe uses a different pattern for setting cal_step (so this PR doesn't yet close spacetelescope/roman_datamodels#343).

This PR does mean that someone could call:

strun ramp_fit ...

But this PR doesn't update the docs to encourage/discourage that (and I think opening and merging #1476 makes sense to do before that).
