1. Make ~/Library//Preferences/rancher-desktop/settings.json non-writable while rd is running. Try to change the version of k8s.

2. Put a non-existent k8s version in ~/Library//Preferences/rancher-desktop/settings.json . Handle the Kubernetes was unable to start with the following exit code message

2.1: The Minikube messages need to be processed to fit in to the current paradigm:

• export MINIKUBE_HOME="$HOME/Library/Application Support/rancher-desktop"
• Use the hyperkit driver, not the docker driver
• Don't dump all the minikube suggestions, just the ones for rebuilding the rancher-desktop profile

Eventually, the app should have a menu command to rebuild it, and the dialog box should point to it, maybe offer a button to fix it right away.
