With PM-2677 backported to v6.0, change stream pipelines containing the $changeStreamSplitLargeEvent stage generate V2 resume tokens by design.

Customers should be able to add this new stage to their existing change stream pipelines and resume using the existing V1 resume tokens, which is v6.0's default. Currently, there is a bug in compareAgainstClientResumeToken() resulting in ChangeStreamFatalError: cannot resume stream; the resume token was not found.
