Issue with Helm Template: kube-rbac-proxy Image Hardcoded

[gioarag]

I have encountered an issue with the Helm Template for the kube-egress-gateway. The image for the kube-rbac-proxy is hardcoded to gcr.io/kubebuilder/kube-rbac-proxy, which prevents the gatewayControllerManager.imageRepository parameter from being effective. This limits the flexibility to specify a different image repository for the kube-rbac-proxy.

Steps to Reproduce:

Deploy the kube-egress-gateway using the provided Helm Template.
Attempt to override the gatewayControllerManager.imageRepository parameter.
Expected Behavior: The gatewayControllerManager.imageRepository parameter should allow specifying a different image repository for the kube-rbac-proxy.

Actual Behavior: The kube-rbac-proxy image remains hardcoded to gcr.io/kubebuilder/kube-rbac-proxy, ignoring the gatewayControllerManager.imageRepository parameter.

kube-egress-gateway Version: v0.0.17
Helm Chart Version: 0.1.4
