permission to watch for referencepolicies are not created by the operator

[raffaelespazzoli]

What steps did you take and what happened:
deploying the operator following the tutorial, I'm getting this error message:

time="2021-11-01T23:57:17Z" level=error msg="pkg/mod/k8s.io/client-go@v0.22.1/tools/cache/reflector.go:167: Failed to watch *v1alpha2.ReferencePolicy: failed to list *v1alpha2.ReferencePolicy: referencepolicies.gateway.networking.k8s.io is forbidden: User \"system:serviceaccount:projectcontour:contour\" cannot list resource \"referencepolicies\" in API group \"gateway.networking.k8s.io\" at the cluster scope\n" context=kubernetes error="<nil>" location="reflector.go:138"

If I try to manually add that permission the operator overwrites the cluster role...

• Software version:

operator image: ghcr.io/projectcontour/contour-operator:main
The operator starts with this logs:

2021-11-01T20:35:06.196Z	INFO	setup	using envoy	{"image": "docker.io/envoyproxy/envoy:v1.19.1"}
