truthy docs?

[pdehaan]

liquidjs has this really handy chart of what is truthy or falsy, but I can't seem to find if Nunjucks has some similar reference: https://github.com/harttle/liquidjs/wiki/Truthy-and-Falsy

I tried hacking together some tests to see the differences between liquidjs and nunjucks behavior but I think the only difference was liquidjs considers an empty string truthy, but nunjucks considers it falsy (which I think is better). 🤷‍♂

Nunjucks follow JS "trythy" logic of types coercion.

But this is likely would change after #1059 (see listed issues).
