Boolean examples look like strings

[Boris Burtin]

Thanks for maintaining this project. I just generated docs for the first time, and they look really good.

I found a minor nit with boolean fields. When a boolean field doesn't have "example" set, the sample JSON looks like this:

"isActive": "boolean"

which implies that the value is supposed to be a string. I think it would be more intuitive if the default was false.

      "id": "integer (int64)",
      "name": "string"
    }

To change those values you can just provide and example block
