Clear kube config when turning off kubernetes

[azdanov]

Is your feature request related to a problem? Please describe.
When turning off Kubernetes support it would be good to clear the current kube config. Similar as how minikube delete removes all the configuration.

Describe the solution you'd like
When turning off kubernetes I would like my kube config to be clear from orbstack specific settings.

Describe alternatives you've considered
At the moment I have to run.

kubectl config unset clusters
kubectl config unset contexts
kubectl config unset users
kubectl config unset current-context

Additional context
When turning on kubernetes the kubeconfig is updated to have orbstack, it can be similar when turning off that it gets removed.
