Subject: [PATCH] doc: Move wal_init_zero and wal_recycle descriptions to
 proper section.

The group of wal_init_zero and wal_recycle is WAL_SETTINGS in guc.c,
but previously their documents were located in
"Replication"/"Sending Servers" section. This commit moves them to
the proper section "Write Ahead Log"/"Settings".

Back-patch to v12 where wal_init_zero and wal_recycle parameters
were introduced.
