This issue is to review existing documentation around Gateways and Ingress Gateways and make any necessary updates for Istio ambient mode.

This means reviewing:

• About Gateways and Gateway Injection docs
• Getting traffic into the mesh via a Service type LoadBalancer or OpenShift Route
• Getting traffic into the mesh via Kubernetes Gateway API

There may not be any changes necessary, but these pages should be reviewed for anything that is sidecar specific or may not be supported with ambient mode. Also consider that workloads may be sidecar only, ztunnel only or ztunnel + waypoint.

Acceptance Criteria:

• Confirm that no changes are needed OR draft the necessary changes to be made.
