Facilitate access to nmdc_materialized_patterns schema variant via PyPI package

[eecavanna]

The task here is to make the same changes (to the nmdc-schema repo) that were made (to the berkeley-schema-fy24 repo) via PR microbiomedata#204 (associated issue is #2062). In other words, changes were made to the berkeley-schema-fy24 repo and I want to make those same changes to this repo (nmdc-schema).

I implemented this in #2091 (awaiting review/merge). The merging of that PR might be dependent upon approval from the Berkeley schema roll out squad members, since we're in a "schema freeze" period.
