adds an example of a boolean knob

[ariesshrimp]

proves that the boolean knob works as expected

Issue:

What I did

How to test

• Is this testable with Jest or Chromatic screenshots?
• Does this need a new example in the kitchen sink apps?
• Does this need an update to the documentation?

If your answer is yes to any of these, please make sure to include it in your PR.

LGTM! @joefraley Is this currently working? Or did you add it to show that knobs boolean is broken?

As an aside, most of the time we look at official-storybook. Never hurts to add an example to a specific view layer tho.
