OperatorGroup RBAC Documentation is outdated

[awgreene]

The OperatorGroup RBAC Documentation is dated as of this commit.

Steps to reproduce:

1. Install OLM
2. Install the elasticSearch Operator with the following command: kubectl create -f https://operatorhub.io/install/elastic-cloud-eck.yaml
3. View the available clusterRoles

$ k get clusterroles
...
# ClusterRoles generated for the `operators/global-operators operatorGroup`.

global-operators-edit                                                  2021-11-05T21:34:28Z
global-operators-view                                                  2021-11-05T21:34:28Z
...

4. Mutiple labels are generated in the operatorGroup's clusterRole

k get clusterroles global-operators-edit -o yaml
aggregationRule:
  clusterRoleSelectors:
  - matchLabels:
      olm.opgroup.permissions/aggregate-to-91302e3d8ef46fe2-edit: "true"
...
...
...

$ k get clusterRoles -l  olm.opgroup.permissions/aggregate-to-91302e3d8ef46fe2-edit=true
NAME                                    CREATED AT
apmservers.apm.k8s.elastic.co-v1-edit   2021-11-05T21:50:54Z

Proposed Fix:

Documentation should be updated to reflect that OLM now generates a label selector for each provided api in the operatorGroup.
