Support Google Artifact Registry

[vijaytdh]

The kubescape operator components don't seem to be able to pull images from Google Artifact Registry. Looking at the code it uses this package https://github.com/kubescape/k8s-interface/blob/main/cloudsupport/cloudvendorregistrycreds.go#L198

But the function below only supports registry URLs that start with "gcr.io"

func CheckIsGCRImage(imageTag string) bool {
	// gcr.io/elated-pottery-310110/golang-inf:2
	return strings.Contains(imageTag, "gcr.io/")
}

This would need to be changed to something like:

func CheckIsGCRImage(imageTag string) bool {
	// gcr.io/elated-pottery-310110/golang-inf:2
	return strings.Contains(imageTag, "gcr.io/") || strings.Contains(imageTag, ".pkg.dev/")
}

Or use some sort of regex.

The only workaround I can think of is to have try to have pull secrets but that's not convenient to have to manage secrets.
