sudo -E minikube image build breaks users ability to use docker build on none driver

The issue I'm running into is with Docker 23, they're deprecating the legacy builder builtin to Docker and want you to also install docker-buildx-plugin.

After implementing #16386, I'm running into a problem when I'm running sudo -E minikube image build as the buildx-plugin creates the file /home/<user>/.docker/buildx/activity/default after a build, but because of sudo -E it has root:root permissions. Then if I try to do a normal docker build after running the above it fails with ERROR: open /home/<user>/.docker/buildx/activity/default: permission denied.

So after running sudo -E minikube image build it essentially breaks the users ability to use docker build unless they change the permissions of /home/<user>/.docker/buildx/activity/default off of root:root.

If you start minikube with sudo minikube start and build with sudo minikube image build it works fine as it writes to /root/.docker/buildx/activity/default instead. But our documentation tells users to use sudo -E minikube.
