The following Session Snapshot failures are occurring in the EG CI:

[2023/04/19 21:52:15.498]     mongotest.go:146: skipping due to environmental constraints: no matching RunOnBlock; comparison errors: [server version "7.1.0-alpha-191-ga756c01" is higher than max version "4.4.99"] 

Here is an example.

From this slack thread, it appears that we are 

incorrectly waiting for the newly inserted document to become visible. Before 7.0 this wasn't a problem presumably because the server snapshotted the document faster than motor could read. The extra latency in 7.0 was long enough for the test to start failing.

MOTOR (MOTOR-1098) and CXX (PR #9522 ) both had this problem in their documentation examples. The Go Driver is experiencing flakiness in the unified spec tests, not the documentation examples.
