doc: adjust wal_level pg_upgrade patch

Since 9.5 has two WAL levels that apply to standby upgrades, archive and
hot_standby, adjust the docs for that version to say, basically, "restore old
cluster wal_level value in the new cluster".

This is a follow-on patch to fd376afc9863dd8ea3eba95edfa79961173e706f.

Backpatch-through: 9.5 only
