Restarting snap.kubelet.daemon service results in failed to parse kubelet flag: unknown flag: --container-runtime

The control plane of my Charmed Kubernetes deployment got blocked because the kubelet service stopped in both nodes.

App Version Status Scale Charm Channel Rev Exposed Message
kubernetes-control-plane 1.27.1 blocked 2 kubernetes-control-plane latest/stable 231 no Stopped services: kubelet
kubernetes-worker 1.27.1 waiting 3 kubernetes-worker latest/stable 87 yes Waiting for kubelet to start.

The charm in trying to restart it, but falls into the following error:

$ sudo snap info kubelet
installed: 1.27.1 (2945) 22MB classic,in-cohort

The upstream documentation says:

--container-runtime string Default: remote
The container runtime to use. Possible values: docker, remote. (DEPRECATED: will be removed in 1.27 as the only valid value is 'remote')

--cloud-provider string
The provider for cloud services. Set to empty string for running with no cloud provider. If set, the cloud provider determines the name of the node (consult cloud provider documentation to determine if and how the hostname is used). (DEPRECATED: will be removed in 1.24 or later, in favor of removing cloud provider code from Kubelet.)

https://kubernetes.io/docs/reference/command-line-tools-reference/kubelet/

The kubelet args looks like this in the snap:
$ cat /var/snap/kubelet/current/args
--kubeconfig="/root/cdk/kubeconfig" --v="0" --node-ip="172.31.20.76" --container-runtime="remote" --container-runtime-endpoint="unix:///var/run/containerd/containerd.sock" --cloud-provider="aws" --config="/root/cdk/kubelet/config.yaml" --pod-infra-container-image="rocks.canonical.com:443/cdk/pause:3.6" --register-with-taints="node-role.kubernetes.io/control-plane:NoSchedule"

To try, I sshed into the kubernetes-control-plane units, manually removed '--container-runtime="remote"' and '--cloud-provider="aws"' from /var/snap/kubelet/current/args since both seem to be deprecated and restarted the snap:

$ sudo snap restart kubelet.daemon

But the charm will overwrite the snap config and restart it again falling in the same error.
