[Help Wanted] Add option to play a default (and configurable) sound when keyboard event triggers

[avasconcelos114]

Description:
Each time the a-keyboard-update event gets triggered, an keypress sound play depending on whether or not the audio option is set to true

Example keyboard sound: https://freesound.org/people/thegreatrazz/sounds/332459/

Outcome

• Logic is added to play a sound on keypress events
• An example has been added to the examples/ directory that displays this behavior
