fix: use v1beta1 version in EKS user kubeconfig

[dkoshkin]

What type of PR is this?
/kind bug

What this PR does / why we need it:

client.authentication.k8s.io/v1alpha1 has been removed in Kubernetes v1.24 see aws/aws-cli#6920. EKS will soon support v1.24, to prepare for that we should use a version that will be supported. This also breaks anyone that uses kubectl >=1.24, so others may already be seeing this issue.

The oldest version that EKS supports is v1.20 https://docs.aws.amazon.com/eks/latest/userguide/kubernetes-versions.html where v1beta1 was already available (and is still available even in 1.26)

# a newer kubectl version does not work
➜  kubectl version --client=true

Ah the last version was 1.19 with alpha, right? So this should be okay and not affect existing clusters.

[dkoshkin]

Looks like 1.10 was the last version with no beta and only alpha https://github.com/kubernetes/kubernetes/tree/release-1.10/staging/src/k8s.io/client-go/pkg/apis/clientauthentication
I doubt anyone is still using that version, and definitely would not be able to install a new cluster with it.
