Queries that used to succeed with no results if not configured correctly will now fail with an error message

Description of Linked Ticket

https://jira.mongodb.org/browse/SERVER-78831 recently fixed a bug with the $listSearchIndexes aggregation pipeline stage to cause it to throw an error when not connected to an Atlas cluster. Example output from 7.0.1:

>  db.adminCommand({ buildInfo: 1 }).version
7.0.1
> db.bar.getSearchIndexes()
MongoServerError: PlanExecutor error during aggregation :: caused by :: Search index commands are only supported with Atlas.

There appears to be a regression in the 7.2 alpha releases. This fix is no longer present and $listSearchIndexes returns an empty array when executed against a non-Atlas cluster. Example from 7.2.0-alpha-39-g3e9f147:

>  db.adminCommand({buildInfo: 1}).version
7.2.0-alpha-39-g3e9f147
>  db.bar.getSearchIndexes()
