RKE2 nginx ingress controller is using hostPort

It appears RKE2 nginx ingress controller is deployed using a configuration with hostPort 80 and 443. Since we expose it through a LoadBalancer Service, it is useless to have this hostPort setting and it should be disabled.

See Kubernetes recommendation:

https://kubernetes.io/docs/concepts/configuration/overview/#services

Don't specify a hostPort for a Pod unless it is absolutely necessary.
