Add missing include in AsyncUDP.h (#6412)

Browse source 
In my project I'm getting the error 
```
In file included from lib/Discovery/Discovery.cpp:2:
C:/Users/David/.platformio/packages/framework-arduinoespressif32/libraries/AsyncUDP/src/AsyncUDP.h:47:1: error: expected class-name before '{' token
```

Adding a reference to Stream.h fixes it.
