Fix duplicate transaction replay during pg_createsubscriber.REL_17_STABLE
Previously, the tool could replay the same transaction twice, once during
recovery, then again during replication after the subscriber was set up.
This occurred because the same recovery_target_lsn was used both to
finalize recovery and to start replication. If
recovery_target_inclusive = true, the transaction at that LSN would be
applied during recovery and then sent again by the publisher leading to
duplication.
To prevent this, we now set recovery_target_inclusive = false. This
ensures the transaction at recovery_target_lsn is not reapplied during
recovery, avoiding duplication when replication begins.
