Update 17-rock-paper-scissors.js

[HarsheedRabhadia]

This update adds output lines to display the choices made by the player and the computer, matching the originally requested format. Now the program outputs:
Example:

**Player picked: Rock
Computer picked: Scissors

The player won!**

Previously, the code only showed the result without specifying the selections.

As I have checked, These changes fixes the current output code as in the tutorial.
