Add version-specific self-hosted-to-cloud instructions for v1.22-v1.23 (#4115)

* Add version-specific self-hosted-to-cloud instructions for v1.22 and v1.23

There's a special-case for v1.22 and v1.23 that should be included in the doc. For now, we aren't aware of enough special-cases that we'd need a dedicated section or page for them.

 ### Additional Notes
 
+#### Special dynamic configuration for Version 1.22.x-1.23.x
+Temporal versions 1.22.x and 1.23.x include support for stream-based replication, but it is disabled by default. Since those releases, stream-based replication has been validated as more reliable than the poll-based replication that remained the default in 1.22 and 1.23. 
+
+When preparing for an S2C migration on these versions, configure the following dynamic settings to enable stream-based replication:
+
+```yaml
+history.enableReplicationStream:
+  - value: true
+```
+
+Enabling this configuration will require a restart of your history pods.
