JP-2349: Add workaround to load old files with new moving_target_table schema

[tapastro]

Resolves JP-2349

This PR addresses validation issues encountered when opening jwst uncal files generated with DMS Ops builds <11.1 and using stdatamodels>=2.1.0. This most recent release of stdatamodels changed the number of columns in the moving_target_table schema, which leads to validation errors when opening any existing file with an old moving target extension. For any users attempting to load an outdated uncal file, this PR will check for the missing columns and add nan-filled columns if they are missing.

I'm running a set of regression tests for completeness: https://plwishmaster.stsci.edu:8081/job/RT/job/JWST-Developers-Pull-Requests/1751/

But this made it through without a regression test failure, which would mean that we don't have a regression test that loads an uncal file with moving target data. This needs to be fixed in a yet-unwritten PR to jwst with a new test.

EDIT: I remember now - bad management advice from yours truly. @emolter modified the test's input file to include the new columns, which of course fixed the test but ignores the problems introduced for all other files. We can get coverage of this workaround by updating the test_nircam_mtimage to use flight data, as all uncals are still missing these columns (unless handcrafted...)

Guess I learned the hard way that this is bad practice... sorry about that. Should have thought it through more
