Overview

`Tapioca::Compilers::Dsl::ActiveSupportConcern` generates RBI files for classes that both `extend` `ActiveSupport::Concern` and `include` another class that extends `ActiveSupport::Concern`

For example for the following hierarchy:

~~~rb # concern.rb module Foo

extend ActiveSupport::Concern
module ClassMethods; end

end

module Bar

extend ActiveSupport::Concern
module ClassMethods; end
include Foo

end

class Baz

include Bar

end ~~~

this generator will produce the RBI file `concern.rbi` with the following content:

~~~rbi # typed: true module Bar

mixes_in_class_methods(::Foo::ClassMethods)

end ~~~
