[PGDOCS] Inconsistent linkends to "monitoring" views.

I noticed one or two "monitoring" links and linkends that are slightly
inconsistent from all the others.

~~~

From "Dynamic Statistics Views"

pg_stat_activity, linkend="monitoring-pg-stat-activity-view" ==> ok
pg_stat_replication, linkend="monitoring-pg-stat-replication-view" ==> ok
pg_stat_wal_receiver, linkend="monitoring-pg-stat-wal-receiver-view"> ==> ok
pg_stat_recovery_prefetch,
linkend="monitoring-pg-stat-recovery-prefetch" ==> MODIFY
linkend="monitoring-pg-stat-recovery-prefetch-view"
pg_stat_subscription, linkend="monitoring-pg-stat-subscription" ==>
MODIFY linkend="monitoring-pg-stat-subscription-view"
pg_stat_ssl, linkend="monitoring-pg-stat-ssl-view" ==> ok

~~~

From "Collected Statistics Views"

pg_stat_archiver, linkend="monitoring-pg-stat-archiver-view" ==> ok
pg_stat_bgwriter, linkend="monitoring-pg-stat-bgwriter-view" ==> ok
pg_stat_database, linkend="monitoring-pg-stat-database-view" ==> ok
pg_stat_database_conflicts,

linkend="monitoring-pg-stat-replication-slots-view" ==> ok
pg_stat_slru, linkend="monitoring-pg-stat-slru-view" ==> ok
pg_stat_subscription_stats,
linkend="monitoring-pg-stat-subscription-stats" ==> MODIFY
