Local Update Server link 404

+++ This bug was initially created as a clone of OCPBUGSM-46761 +++

Description of problem:
When using the admin console, under "Cluster Settings" and choosing Upstream Configuration, the "window" that appears has a dead link to documentation for how to create a local (disconnected) update server.

The link in the window is
https://access.redhat.com/documentation/en-us/openshift_container_platform/4.10/html/updating_clusters/installing-update-service

Assume the right link should be something like:
https://docs.openshift.com/container-platform/4.10/updating/updating-restricted-network-cluster.html#update-restricted-network-cluster-update-service

Version-Release number of selected component (if applicable):

4.10.*
