OCPBUGS-32887: Allow operator to update Route spec.subdomain

[Miciah]

Before this change, cluster-ingress-operator did not have permission to update spec.host or spec.subdomain on an existing route as the operator's serviceaccount did not have the necessary "routes/custom-host" permission. #965 added logic to the operator to clear spec.host and instead set spec.subdomain, but without the required permission, the update would fail with the following error message:

ERROR   operator.init   controller/controller.go:265    Reconciler error {"controller": "canary_controller", "object": {"name":"default","namespace":"openshift-ingress-operator"}, "namespace": "openshift-ingress-operator", "name": "default", "reconcileID": "463061e3-93a1-4067-802e-03e3f1f8cdd0", "error": "failed to ensure canary route: failed to update canary route openshift-ingress-canary/canary: Route.route.openshift.io \"canary\" is invalid: spec.subdomain: Invalid value: \"canary-openshift-ingress-canary\": field is immutable"}

This PR adds the needed permission to the clusterrole for the operator's serviceaccount so that the update can succeed.

The e2e-aws-operator, e2e-gcp-operator, and e2e-azure-operator jobs all failed on TestRouteAdmissionPolicy, but e2e-aws-operator passed in #1048, so I'm not sure whether we have a new flake, or an extremely rare old flake, or what.
/test e2e-aws-operator
/test e2e-azure-operator
/test e2e-gcp-operator

The TestRouteAdmissionPolicy failure is being tracked as part of OCPBUGS-26498.

[Miciah]

ci/prow/e2e-azure-operator failed because these tests failed:

• TestRouteAdmissionPolicy — this is OCPBUGS-26498.
• TestManagedDNSToUnmanagedDNSIngressController — I see this failing on 1 other PR.
• TestAllowedSourceRanges — failing on other PRs.
• TestSourceRangesProgressingAndEvaluationConditionsDetectedStatuses — only failed on this PR; I'll watch for a re-occurrence of this failure.
• TestAllowedSourceRangesStatus — only failed on this PR; I'll watch for this one too.
• TestUnmanagedDNSToManagedDNSInternalIngressController — failing on other PRs.
