7.6 what's new in staging has arbiter node info in wrong section

In https://docs-staging.couchbase.com/server/7.6/introduction/whats-new.html , the arbiter node info is in the wrong section (Backup and Restore), instead of in the Cluster Manager section.

You can add one or more arbiter nodes to a cluster. An arbiter node helps your cluster in two ways:

It provides fast failover which helps decrease the cluster’s latency when reacting to a failover.

It provides quorum arbitration that helps avoid contention issues if the nodes in the cluster become partitioned.

^^ The above info is currently in the Backup and Restore section of What's New, but it belongs in the Cluster Manager section.
