The gatekeeper operator is transitioning from a component delivered with ACM to a component that is separate.  From a support perspective, the customer still needs to purchase either OPP or ACM, but from a product perspective, that means gatekeeper can be used without ACM.  Having the gatekeeper documentation in ACM only is therefore not a good experience since we want customers to access gatekeeper documentation directly.

What we have now is in the Governance chapter.  https://access.redhat.com/documentation/en-us/red_hat_advanced_cluster_management_for_kubernetes/2.8/html/governance/governance#gatekeeper-policy

Describe the changes in the doc and link to your dev story

Provide info for the following steps:

1. - [x] Mandatory Add the required version to the Fix version/s field.

2. - [x] Mandatory Choose the type of documentation change.

      - [x] New topic in an existing section or new section
      - [ ] Update to an existing topic

3. - [x] Mandatory for GA content:
            
       This request is to create a new document.  This would be separate from the current ACM documentation.  The new document would need updates consistent with the gatekeeper releases – separate from the ACM releases.

Existing content in the ACM documentation for gatekeeper will remain.  The current content is mostly focused on using Gatekeeper with ACM policies.  It will be valuable for the ACM content to reference the new document too.
