Description:
There is a problem resolving .Values.topologyInjector.enabled in _rbac.tpl file due to how it is being referenced in envoy-gateway-rbac.yaml.
On line 22 it is passing the range context to the template instead of the root context, which in turns leads to a problem resolving .Values.topologyInjector.enabled in _rbac.tpl.

Repro steps:
Example config:

config:
  envoyGateway:
    provider:
      kubernetes:
        watch:
          type: Namespaces
          namespaces:
            - namespace1
            - namespace2

helm template oci://docker.io/envoyproxy/gateway-helm --version 1.3.2 -f example.yaml
helm template oci://docker.io/envoyproxy/gateway-helm --version 1.4.0-rc.2 -f example.yaml

With 1.3.2, the above works well, but with 1.4.0-rc.2, it produces this error:
Error: template: gateway-helm/templates/envoy-gateway-rbac.yaml:22:3: executing "gateway-helm/templates/envoy-gateway-rbac.yaml" at <include "eg.rbac.namespaced" .>: error calling include: template: gateway-helm/templates/_rbac.tpl:12:14: executing "eg.rbac.namespaced" at <.Values.topologyInjector.enabled>: can't evaluate field Values in type string

Environment:
version 1.4.0-rc.2

Proposed fix in #5902
