[TestKit] SupervisorStrategy for TestActor is unused

[roee88]

Version Information

v1.5

Describe the bug

https://github.com/akkadotnet/akka.net/pull/4148 added public IActorRef ChildActorOf(Props props, string name, SupervisorStrategy supervisorStrategy) and similar methods to TestKitBase. However, the supervisorStrategy does not take effect.

It looks like InternalTestActor doesn't override SupervisorStrategy() to actually use its private _supervisorStrategy. See https://github.com/akkadotnet/akka.net/blob/0782c7dc069618e20a3791aaab667076f487ad96/src/core/Akka.TestKit/Internal/InternalTestActor.cs#L24
