Possible inaccuracy in description of ztunnel load balancing #16659

Description

@Dylan-KW

In the following section of the documentation:
https://istio.io/latest/docs/ambient/usage/troubleshoot-ztunnel/#verifying-ztunnel-load-balancing

The sentence reads:

"~ If the destination service is configured to use one or more waypoint proxies, then the source ztunnel proxy performs load balancing by distributing traffic across these waypoint proxies and sends traffic via the remote ztunnel proxies on the node hosting the waypoint proxy instances."

This seems to conflict with the data plane behavior described in the architecture docs here: https://istio.io/latest/docs/ambient/architecture/data-plane/#in-mesh-routing-with-waypoint-enabled

It might be clearer and more accurate to say something like:

"~ If the destination service is configured to use one or more waypoint proxies, then the source ztunnel proxy performs load balancing by distributing traffic across these waypoint proxies and sends traffic directly to the waypoint, which then forwards the traffic."

Please let me know if my understanding is incorrect.
