Description

LoggingTestKit requires logback-classic library to be on the classpath. We can see this in the implementation at https://github.com/akka/akka/blob/master/akka-actor-testkit-typed/src/main/scala/akka/actor/testkit/typed/internal/LoggingTestKitImpl.scala#L120

log4j2 (https://logging.apache.org/log4j/2.x/) is the successor to logback and it will be great to move the dependency in LoggingTestKit to use log4j2 instead.

Contributor guide

Research direction
