Explain how to instantiate altDriver

[gomboskriszta15]

In docs we explain nowhere how to instantiate altDriver. We just simply use it.

In the Java example, if you try to use the code line in a test, you will get a syntax error, the host: and port: should be removed to get the code working ( in both the Unity and Unreal sections).

Considering this, I will reopen the ticket.
