Cop idea: Negative #valid? method

[ydakuka]

Actual behavior

I have the code:

class AdvertsController < ApplicationController
  # PATCH /adverts/:id
  def update
    render :edit unless @form.valid?
  end
end

I run rubocop:

ydakuka@yauhenid:~/Work/project$ bin/rails_docker rubocop spec/forms/advert_form_spec.rb
Inspecting 1 file
.

1 file inspected, no offenses detected

Expected behavior

I expected to receive the following code:

class AdvertsController < ApplicationController
  # PATCH /adverts/:id
  def update
    render :edit if @form.invalid?
  end
end

This should be handled by existing Style/InvertibleUnlessCondition cop - https://docs.rubocop.org/rubocop/1.52/cops_style.html#styleinvertibleunlesscondition
