Need to fix the broken links for Standard and Brokered in this content: https://doc-stage.usersys.redhat.com/documentation/en-us/red_hat_amq/7.6/html-single/installing_and_managing_amq_online_on_openshift/index#con-address-space-messaging-planning-planning

Solution is to implement a new attribute for the Using guide URL by:
1. Implementing

in the upstream content
2. Adding the following attribute to the downstream:
UsingGuideUrl: /html-single/using_amq_online_on_openshift/

(Upstream issue: https://github.com/EnMasseProject/enmasse/issues/4158)
