grpcgen_test.go:185: Error in resolve no matching virtual host found for ""}

I note an update in the github.com/grpc/grpc-go update also included in this PR which has a noted change xds: fix a bug that results in no matching virtual host found RPC errors due to a difference between the target and LDS resource names

grpc/grpc-go#6997 seems to move from using:

	endpoint := target.URL.Path
	if endpoint == "" {
		endpoint = target.URL.Opaque
	}
	endpoint = strings.TrimPrefix(endpoint, "/")

to using

target.Endpoint()

Requires a change in https://github.com/istio/istio/blob/master/pilot/pkg/networking/grpcgen/grpcgen_test.go#L172-L174 or a regression in grpc-go?

Likely superseded by #50129
