Description

Add some explanation and example code on how to achieve Scatter Gather First Completed under https://doc.akka.io/docs/akka/current/typed/interaction-patterns.html

Scatter Gather First Completed delivers a message to multiple actors, waits for the first reply, and then sends it to the original requestor. Other replies are ignored. See also: https://doc.akka.io/docs/akka/current/routing.html#scattergatherfirstcompletedpool-and-scattergatherfirstcompletedgroup
