Subject: Retrieve 'ProbeSet' trait name

Issue:
https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/clustering.gmi

* gn3/db/traits.py: new function (retrieve_probeset_trait_name)
* tests/unit/db/test_traits.py: test(s) for new function

  Add a function to retrieve the name of a 'ProbeSet' trait in a manner
  similar to genenetwork1's retrieval of the same, as implemented here
  https://github.com/genenetwork/genenetwork1/blob/master/web/webqtl/base/webqtlDataset.py#L140-154

  Unlike in genenetwork1, we do not mutate an object, instead, we return the
  values as retrieved from the database, and the caller will deal with the
  returned values as appropriate.
