Use runCtx instead of of config.Opts for suggesting suggestions.

Relates to #5485

This is a refactor, to break change in smaller PR for #5485.
When adding deploy error codes #4933, i missed the part where kubectx gets called directly. We have that information in runCtx. It easier to use the evaluated context there instead of re-writing logic to look up kubeContext

Pros

1. Remove dependency on pkg/skaffold/config and pkg/skaffold/kubernetes/context from errors.
2. In upcoming PR, we need the logic to determine minikube vs remote cluster for "Internal System Error". Using runCtx is much easier than again evaluating kubecontext in deploy/errors package.
