Describe the requested changes

Multiple VirtualHostOptions examples in GG docs fail because targetRefs are not list-formatted.

Example:

% kubectl apply -n gloo-system -f- <<EOF
apiVersion: gateway.solo.io/v1
kind: VirtualHostOption
metadata:
  name: header-manipulation
  namespace: gloo-system
spec:
  options:
    headerManipulation:
      requestHeadersToAdd:
        - header:
            key: "my-header"
            value: "gloo-gateway"
  targetRefs:
    group: gateway.networking.k8s.io
    kind: Gateway
    name: http
    namespace: gloo-system
EOF
Error from server (BadRequest): error when creating "STDIN": VirtualHostOption in version "v1" cannot be handled as a VirtualHostOption: strict decoding error: unknown field "spec.targetRefs.group", unknown field "spec.targetRefs.kind", unknown field "spec.targetRefs.name", unknown field "spec.targetRefs.namespace"
