Issue description

Description:  In Step 9.5 of the Cluster Self-Service Setup lab, it mentions using this label/value: "network.openshift.io/policy-group: ingress" I am practicing looking things up in the documentation (there's still way too much rote memorisation for me to deal with this successfully). And I happened to notice I was having a tough time searching for "network.openshift.io/policy-group" but I eventually figured out how to find it and apparently this is now a legacy label and "policy-group.network.openshift.io/ingress has become the preferred namespace selector label for OpenShift SDN[1]. What I'm wondering is: Are both of these acceptable for grading? Would the new label, if I happened upon it and used it instead, still work in an exam environment? https://docs.openshift.com/container-platform/4.12/networking/network_policy/multitenant-network-policy.html 

Steps to reproduce:

policy-group.network.openshift.io/ingress: "" is the preferred namespace selector label for OpenShift SDN

network.openshift.io/policy-group: ingress namespace selector label, but this is a legacy label.

Workaround:

Expected result:
