docs: explain minikube detection (#6512)

Also explaining how to find current context as many k8s newbies might not know
this. It's also worth debating calling this term "kubectl context" instead of
"kubernetes context", as Kubernetes does not have this notion, only kubectl
does.

+```bash
+kubectl config current-context

+
+Skaffold checks for the following context names:
 
 | Kubernetes context | Local cluster type | Notes |
 | ------------------ | ------------------ | ----- |
 | docker-desktop     | [`Docker Desktop`] | |
 | docker-for-desktop | [`Docker Desktop`] | This context name is deprecated |
-| minikube           | [`minikube`]       | |
+| minikube <sup>1</sup> | [`minikube`]    | See <sup>1</sup> | |
 | kind-(.*)          | [`kind`]           | This pattern is used by kind >= v0.6.0 |
 | (.*)@kind          | [`kind`]           | This pattern was used by kind < v0.6.0 |
 | k3d-(.*)           | [`k3d`]            | This pattern is used by k3d >= v3.0.0 |
 
 For any other name, Skaffold assumes that the cluster is remote and that images
 have to be pushed.
 
+<sup>1</sup> Additionally, a Kubernetes context may be considered as `minikube`
+even if it's not named `minikube` but it's cluster certificate is stored at
+`$HOME/.minikube` or the `minikube profile list` command returns the Kubernetes
+context name.
