The potentiometer is not keyboard accessible

[urish]

The potentiometer should be able to receive input focus and react to keyboard input, implementing the ARIA slider role:

This means we should respond to Left, Right, Up, Down, Page Up, and Page Down keys.
In addition, we could also support Home and End keys, similar to how <input type="range"> to these events in chrome: setting the value to the start or end of the range.

You can check tinker with the current version of the potentiometer here: https://elements.wokwi.com/?path=/story/potentiometer--potentiometer
