Kiali - remove legacy istio operatorful component status pod labels

Package Merge Request

BB Level Changes

• This MR resolves a cluster status error in displayed in Kiali: public Not found
• This is caused by old helm templating used in the legacy Istio Operator-ful deployments. This obsolete code sets a gateway "public" pod label in the chart/templates/kiali/values.yaml under the upstream.cr.spec.external_services.istio.component_status.components path.
• During testing I validated that the correct gateway pod labels are still being dynamically generated and applied. You can see the "passthrough-ingressgateway" and "public-ingressgateway" labels displayed in the screenshot below.
