I was thinking as part of the eval $(minikube docker-env) we could pass something that changes the terminal Prompt so it is obvious for the user they are usinf minikube's docker not their own docker.

maybe:
something like:

medya@~ $ PS1="$PS1""(using minikube dockerd) $:"

that will try turn into

medya@~ $ (using minikube dockerd) $:

the minikube word would be profile name, this will also make it clear which profile's docker-env we are using.

helps with #6462
helps with #6437

also we could explicity set a ENV that says

USES_MINIKUBE_DOCKERD=PROFILE_NAME
