Support go-containerregistry as a new image resolver

go-containerregistry is a golang library for working with container registries. By supporting this library as a new resolver, we don't need Docker dependency anymore (save & pull stuff in pipeline) since we are able to talk directly with registries. I'm not sure if this is a straightforward task to implement but all we need to do is write a simple converter to convert go-containerregistry models into dives'.
