Alphabetize reordered data source menu

[nmdefries]

Summary:

Context

When using the nav_order setting in markdown front matter, pages sharing the same nav_order are alphabetized by filename, NOT by title. For existing pages, change filenames to alphabetize properly but specify permalink to keep URLs the same.

(For new pages, filenames should be set to match page titles so that alphabetization is correct. Adding permalinks is unnecessary.

We could also force alphabetization using nav_order, but this approach minimizes future work. That is, we won't have to keep inserting new nav_order values between existing ones. All new inactive data sources will be assigned nav_order: 2; active ones will have nav_order: 1.)

Also mention "NHSN" in hhs documentation.
