apiextensions.k8s.io/v1beta1 CustomResourceDefinition is deprecated in v1.16+, unavailable in v1.22+;

Describe the bug
I'm currently using application-gateway-kubernetes-ingress (AGKI) v1.40. I've just updated to AKS version 1.21.2 and seeing this warning:
apiextensions.k8s.io/v1beta1 CustomResourceDefinition is deprecated in v1.16+, unavailable in v1.22+;

I've also created a fresh aks cluster using 1.22.2 and wasn't able to install AGKI on it.

To Reproduce
Create a cluster with AKS v.1.21.2 and install AGKI v1.4.0 => warning
Create a cluster with AKS v.1.22.2 and try to install AGKI v1.4.0 => error

Looks like there's already a PR open for this for some time.
I wander what's taking so long, this is a blocker for v1.22+

Do not do this!

I've just upgraded an existing AKS cluster to version 1.22.2 (very foolish)
now AGIC is broken; adding an Ingress does nothing. Listeners, rules etc. are no longer created in App GW

I can see that AGIC has upgraded, it was 1.4:
mcr.microsoft.com/azure-application-gateway/kubernetes-ingress:1.5.0-rc1 app=ingress-appgw

I have tried many things...

annotations:
# deprecated as of 1.22
#kubernetes.io/ingress.class: azure/application-gateway

changed Ingress to add spec.ingressClassName

spec:
ingressClassName: azure-application-gateway

fixing the yaml (removed beta.)

nodeSelector:
beta.kubernetes.io/os:

And on discovering this error message: ingresses.networking.k8s.io is forbidden: cannot list resource "ingresses" in API group "networking.k8s.io" at the cluster scope.

I found that networking.k8s.io is missing from ClusterRole!

@CJJ69 Thank for sharing! Will straight away get to fixing this.

Any update on this? I've updated our Pre-Prod clusters to 1.22 and had adjust AGIC to use 1.5.0rc1 to make this work.
But for now we're waiting to roll out the new version until this is solved.

Hi @akshaysngupta. Has this this issue been resolved or targeted to a release?
