       This  function queues an update as part of a bulk operation. It will only modify a single document on the
       MongoDB server. This function does not execute the  operation.  To  execute  the  entirety  of  the  bulk
       operation call mongoc_bulk_operation_execute().

       This function is superseded by mongoc_bulk_operation_update_one_with_opts().
