Subject: [PATCH v2] doc: Mention idle_replication_slot_timeout in
 pg_replication_slots docs.

The pg_replication_slots documentation previously mentioned only
max_slot_wal_keep_size as a condition under which the wal_status column
can show unreserved or lost. However, since commit ac0e33136ab,
idle_replication_slot_timeout can also cause this behavior when it is set.
This was not documented.

This commit updates the documentation to also mention
idle_replication_slot_timeout as a factor that can cause wal_status
to become unreserved or lost.
