There are workflows that rely on `az aks install-cli` to get kubectl
installed. There is a well-known problem on install-cli, related with
API usage rate limit, that has recently caused the command to fail
quite often.
This is replacing install-cli with the azure/setup-kubectl github
action which has no such as rate limit problem.
While here, removed the install_cli() function from gha-run-k8s-common.sh
so avoid developers using it by mistake in the future.
Fixes#11463
