Add rs IDs to the credible set tables in PheWeb

[sync-by-unito]

Some senior members are taking these credible set chr:pos listings in PheWeb and looking up the rsIDs in Gnomad, so seems would be a better use of of their time if they were just listed in the table.

The work to include rsid in the table is done on frontend, relevant PR: #184
It is out of date and conflicts. Also, if the userresults PR of #312 is merged, the rsid data will not be sent by default to frontend from api -> need to add it to the returned data.
