docs: Add cgroupDriver for containerd

Browse Source 
This commit updates the "Run Kata Containers with Kubernetes" to include
cgroupDriver configuration via "KubeletConfiguration". Without this
setting kubeadm defaults to systemd cgroupDriver. Containerd with Kata
cannot spawn conntainers with systemd cgroup driver.

Fixes: #4262
