Prevent image prune from de-tagging Kubernetes control plane images when in containerd storage mode

Description

Normally, the docker prune commands don't delete Kubernetes control plane images that Docker Desktop pulls as part of the Kubernetes setup. But, when you select the new containerd storage option in General settings, the prune commands will delete or de-tag control plane images.

As far as I can tell, Docker Desktop re-pulls these images after restart and doesn't lose the etcd data, so I don't think there's a long-lasting effect of including control plane images in the prune, but I feel it's a confusing and inconsistent behavior.

Reproduce

Enable Kubernetes in default Docker Desktop setup
Run docker image prune --all --force and it will not touch the DD internal K8s images for control plane (but it will delete any image w/o a container attached)
Enable "Use containerd for pulling and storing images" in General settings
Wait for Kubernetes to reinstall in new image store
Run docker image prune --all --force and it will delete some layers and de-tag most K8s control plane images

Expected behavior

The image prune command would behave the same in either dockerd or containerd storage mode.
