kubernetes-json-schema persists after removing kubernetes extension from vs code

[pmeaney]

Hi Yannh,

Just wanted to bring your attention to a problem with the vs code Kubernetes extension-- json file definitions which the K8s extension apparently installed are left behind as artifacts after uninstalling the vs code k8s extension. (This is my assumption)

A link to the issue I posted on k8s extension github: vscode-kubernetes-tools/vscode-kubernetes-tools#1138

(Screenshot attached showing the artifact points to your kubernetes-json-schema)
