Fix template typo

[spowelljr]

Related #12509

Problem:
The kubelet was set to use the docker socket if container runtime was set to cri-o due to typo in template.

Before:

$ minikube start --driver=docker --container-runtime=crio
...
🏄  Done! kubectl is now configured to use "minikube" cluster and "default" namespace by default

$ minikube ssh -- cat /etc/systemd/system/kubelet.service.d/10-kubeadm.conf
[Unit]
Wants=docker.socket
...

After:

$ minikube start --driver=docker --container-runtime=crio
...
🏄  Done! kubectl is now configured to use "minikube" cluster and "default" namespace by default

$ minikube ssh -- cat /etc/systemd/system/kubelet.service.d/10-kubeadm.conf
[Unit]
Wants=crio.service
...
