[Bug] GraphQL - User.topRepositories requires an order

The topRepositories field of the User object requires an orderBy argument. However, the description for topRepositories states that they are “ordered by contribution rank”. I’ve found that the orderBy argument is straight-up ignored no matter what I put in it, and yet it’s required. I believe this is a bug.

This is my first time using GraphQL, so it’s not unlikely that I’m wrong; this just doesn’t seem correct.
