GO-2026-5373: Radius Controller May Delete a Container Resource via an Injected Deployment Annotation (Multi-Tenant Installs) in github.com/radius-project/radius
NewCommand creates a new Cobra command for uninstalling Radius from a Kubernetes cluster, which takes in a factory
object and returns a Cobra command and a Runner object.
Run checks if Radius is installed on the Kubernetes cluster, and if so, uninstalls it, logging a success message
if successful. It returns an error if an error occurs during the uninstallation.
