Bug: Unsorted stream bookmark missing greater-than comparison

Reported by @pierre de Poulpiquet in slack:

While reading the SDK code, I couldn’t really understand how it would perform with a stream of un-sorted records with a replication key.

https://gitlab.com/meltano/singer-sdk/-/blob/main/singer_sdk/helpers/_state.py#L178

Here, the code to increment the state doesn’t seem to check that the new replication key value is “after” the previous replication key value, is it?
