      We decided in 6WR with the product team that we won't be supporting nested $rankFusions or $scoreFusions.

       

      In both these cases, the error message for an invalid pipeline states that a $scoreFusion or $rankFusion is ok - so we need to update these messages.

       

      Also, write explicit unit + jstests for the banning of nested $rankFusions and $scoreFusions, and ensure the provided error message makes clear that these input pipelines are disallowed for the right reason (the error message does not need to explicitly mention "nesting").
