In the context of SPM-3796, it has introduced some new aggregation stage aliases, and its desugared pipeline begins with $queue.

Currently, $unionWith only supports running aggregation stages that start with $queue as the first stage of the pipeline. As a result, it does not recognize aggregation stage aliases, such as $clusterTopology, that its desugared pipeline starts with $queue until SERVER-59628 is completed.

The purpose of this ticket is to incorporate all new aggregation stage aliases into the $unionWith acceptance list.
