More Simple I/O

play-with-turns must show the state of the pile before each turn.

Task: Write a procedure display-game-state that takes a game state as an argument and has behavior like:

     (display-game-state (make-game-state 5 8))


        Pile 1: 5 
        Pile 2: 8 
This output is a side effect, not a value of the display-game-state expression.

Use the Racket procedure display:

          (display object)
which displays object on the screen, and
          (newline)
which causes the output to go to a new line.
