While trying to setup kube-goat in a kind cluster I faced this error: ``` ERROR: failed to create cluster: unknown apiVersion: kind.sigs.k8s.io/v1alpha3 ``` Looking at the [kind](https://kind.sigs.k8s.io/docs/user/configuration/) documentation, the apiVersion string in config.yaml needs to be updated to: ``` apiVersion: kind.x-k8s.io/v1alpha4 ```
