Update default astrometry catalogs used for a posteriori processing

[stscijgbot-hstdp]

Issue HLA-486 was created on JIRA by Warren Hack:

New astrometric catalogs get added to the guide star catalog web service.  Recently, the Early-Release of the GAIA DR3 catalog (labelled, GAIAedr3) was added as a new catalog to the web service.  A new Pan-STARRS catalog which has been fit to the GAIADR2 catalog as well as the full GAIA DR3 release will be added to the web service in the near future.  

These additions should be included as high priority options when performing a posteriori processing during standard pipeline calibration processing with AstroDrizzle.

All mentions of "GSC" anywhere in the code:
haputils/astrometric_utils.py:403:def find_gsc_offset(image, input_catalog='GSC1', output_catalog='GAIA'):
hapsequencer.py:941:    # Every image should (!) have an IDC_?????????-GSC240 solution.
hapsequencer.py:942:    wcs_preference = ['IDC_?????????-GSC240', 'IDC_?????????']
haputils/astrometric_utils.py:273:def get_catalog(ra, dec, sr=0.1, epoch=None, catalog='GSC241'):

Resolved with #986.
