add missing rtdata.output assignments to repointed tests

[braingram]

2 regression tests that may generate new truth files don't have rtdata.output set following: #1426
This results in no file being available for 'okifying'. This PR sets rtdata.output for those 2 tests.

Regression tests all pass: https://github.com/spacetelescope/RegressionTests/actions/runs/11305239809

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
