Allow boolean array [true, false] to be a valid argument for BooleanValidator

[PanosCodes]

How

• Allow BooleanValidator to be build using [true, false] as argument.
• Remove the [true, false] handling from Swagger generator

---

It would probably be easier to review per commit

Looks good, I'm slightly afraid this could introduce a breaking change... ?

[PanosCodes]

We can always put it behing and setting for example

Apipie.configure do |config|
  config.validator.boolean.handle_boolean_array = false
end

My question is why use [true, false] in the first place instead of :bool or :boolean ?
and if we decide to allow [true, false] to be passed as validator should we also allow [1, 0]

I can't think any compelling reason to do so and I'm leaning on closing this PR 😅 (we can use the tests refactoring in another PR)

I don't know, we can keep it open for a while and wait if others wants to chime in their opinion.

[mathieujobin]

if you want to solve the conflict after the refactor, I will merge this as well.

Thanks, I wasn't exactly sure about the spec removal...
