HLA-1402: Fix failing pytests

[s-goldman]

Resolves HLA-1402

This PR addresses the failing pytests on github actions.

test_align.py:

• Due to recent changes to the required number of n_matches, some of the expected WCS solutions are no longer valid. One dataset "ib2u12" no longer achieves a GaiaDr2 solution, as a result this dataset has been removed (temporarily commented out) from the test's input list.

test_asn_regress:

• The test is currently passing when triggered manually using linux or mac. A problem occurs, however, when the test is run using our new github actions tests. When the astrodrizzle call is run, a dependency call to stsci.tools.asnutils.readASNTable fails to read in the association (asn) file. While testing, I was able to confirm that the file is downloaded to the correct location, but it is apparently empty: ValueError: The truth value of an empty array is ambiguous.

Checklist for maintainers

Once we are up and running on GA and not under pressure for a build, we should discuss which test to improve, add, and/or eliminate!
