Discrepancy regarding the default load balancing strategy in Istio

[adityasamant25]

There is a discrepancy in the docs regarding the default load balancer strategy that Istio uses to route traffic among different versions of a service.

In the Request Routing task, it is mentioned:
This is because without an explicit default service version to route to, Istio routes requests to all available versions in a round robin fashion.

In the Traffic Management concepts section, under Load balancing options, it is mentioned:
By default, Istio uses a least requests load balancing policy, where requests are distributed among the instances with the least number of requests.

I believe the default is lead requests load balancing policy and the Request Routing task page may need a fix.

I am awaiting a confirmation on this assumption. If confirmed, I can issue a PR for the fix.
