doc: Correct description of restart_lsn in pg_replication_slots

Previously the document explained that restart_lsn indicates the LSN of
oldest WAL won't be automatically removed during checkpoints. But
since v13 this was no longer true thanks to max_slot_wal_keep_size.

Back-patch to v13 where max_slot_wal_keep_size was added.
