Honey the pick description of Bool.rakudoc

I found the `Bool` page's `pick` doc hard to understand.¹ I eventually figured it out.² I have tried to improve it so it's easier to understand, especially for concrete thinkers.³

¹ I initially thought that the `Bool` class's `pick` was perhaps an especially powerful abstraction which made it a bit difficult to describe and understand, but was ultimately worth the mental effort.

² I concluded the doc was probably just unhelpfully abstract. (Perhaps it was originally copy/pasted from some other class's `pick`?)

³ I concluded the `Bool` variant of `pick` was nice and easy, and I just needed to distill its simplicity while remaining technically correct.
