False positive of UtilityFunction for class methods

[VladYermakov]

Hi there

I've observed a false positive for UtilityFunction when class methods are defined under class_methods block of ActiveSupport::Concern

For instance

module SomeModule
  extend ActiveSupport::Concern

  class_methods do
    def some_method(arg1, arg2)
      return 1 if arg1.something?
      return 2 if arg2.something_else?

      3
    end
  end
end

So here I'm getting UtilityFunction warning, but it makes no sense, and by definition it wouldn't warn this method was defined using self.

Thanks in advance

Reproduced in version 'reek', '~> 6.0' and the warning still occurs.

Can I open a PR to fix the issue?
