Remove dependency on pod-infra-container-image kubelet command flag

[sriramandev]

kubernetes/kubernetes#133779 will remove the --pod-infra-container-image flag from kubelet's command line in 1.35.

images/capi/ansible/roles/kubernetes/defaults/main.yml has dependency on the flag. Need to make sure this no more exists.

/cc @mboersma Looks like a place was missed in the PR ☝️

That reference was left in on purpose. If you read the review comments, we thought it would be safer to have kubeadm remove this flag.
