While backporting the changes in SERVER-44422 to 6.0, some asserts in `stale_mongos_updates_and_removes.js` and `extract_shard_key_values.js` were expected to succeed on 6.0 and not 5.0 (as the ticket had not been backported to 5.0). As a result, I had to edit the tests to check for version number, and perform a different assert based on that version number. But now that the ticket has been backported to 5.0 the version check is no longer relevant and needs to be removed.
