Implement `translate_to_mouse_gene_id` function

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

* Migrate the `web.webqtl.correlation/CorrelationPage.translateToMouseGeneID`
  function in GN1 to GN3.
  This is a function that retrieves data from the database, and therefore uses
  a system outside of our code, therefore, the function does not have a
  corresponding unit test.

  This kind of function will probably need to be tested at the integration or
  system tests level, where we test that our code interacts correcly with any
  and all external systems that it should.
