Get subarray lists from datamodels schema

[bhilbert4]

Resolves #1389

Rather than relying on manually provided subarray lists (which had been missing some entries), get subarray lists from the subarray schema file in the stdatamodels package. This ensures that all available subarrays will be present on the JWQL query page.

One downside to this is the way the schema file is read in. Since the instrument names are in commented lines in the schema file, the subarray lists are accessed through hard-coded indexing. If the order of the instruments' lists ever change in the schema file, we would need to update this code. That seems pretty unlikely though.

Local testing looks good.

Ready for review.

Thanks @bhilbert4 let's hope the schema doesn't change 🤞

Just checked locally, subarrays are appearing for FGS and NIRSPEC:

@bhilbert4 If these look correct, I will merge.

Those look right to me!
