Bug fixes for tests due to spacetelescope/rad#250 and spacetelescope/rad#258

[WilliamJamieson]

spacetelescope/rad#250 and spacetelescope/rad#258 broke some roman_datamodels tests because they were checking features by running tests on models and checking the results against the schemas. This PR updates that data.

Checklist

• Added entry in CHANGES.rst under the corresponding subsection
• updated relevant tests
• updated relevant documentation
• Passed romancal regression testing on Jenkins / PLWishMaster. Link: https://plwishmaster.stsci.edu:8081/job/RT/job/romancal/XXX/

There will be failures in the CI for this because #172 has not been merged.
