Add a note about replacing custom certificates: about  secret that contains the wildcard certificate chain and key  

    from 4.13

Documentation Reference: 
https://docs.openshift.com/container-platform/4.14/security/certificates/replacing-default-ingress-certificate.html


Add a note specifying that when custom ingress certificates needs to be updated, it is not required to rollout the router deployment unless the secret is renamed. 

Something like:

NOTE:"In case of modification or renewal of wildcard certificate chain and key: the router pod deployment will perform a rolling update of the router pods if the secret's name changes. However, it will not trigger a rolling update for just updating the secret's contents as kubelet automatically propagates changes to the secret to the volume mount."

In case of issues reference to KCS https://access.redhat.com/solutions/4542531 should be pointed. 

    missing information about update of the certificates
