Create Print_Hello.ino a basic tutorial on how to use the Keyboard Library

[AsherThomasBabu]

An example that is already present in the Arduino.cc website, but missing in the official libraries.

Note that this is one of the reference examples, not one of the tutorial sketches: https://www.arduino.cc/reference/en/language/functions/usb/keyboard/keyboardwrite/#_example_code

I do like the idea of providing a minimal "hello world" type of example sketch, but https://www.arduino.cc/reference/en/language/functions/usb/keyboard/keyboardprint/#_example_code would probably be better for that purpose, since the use of the ASCII value in this example adds an extra level of complexity for the beginner.
