Improve Rails/HttpStatus cop

Reference: https://rails.rubystyle.guide/#http-status-code-symbols

Actual behavior

If I have the following code:

# frozen_string_literal: true

class ProductsController < ApplicationController
  def index
    render status: '403'
  end
end

or

# frozen_string_literal: true

class ProductsController < ApplicationController
  def index
    render status: 'forbidden'
  end
end

I will run rubocop and not get any offences:

ydakuka@yauhenid:~/Work/project$ bin/rails_docker rubocop app/controllers/products_controller.rb 
Inspecting 1 file
.

1 file inspected, no offenses detected

Expected behavior

# frozen_string_literal: true

class ProductsController < ApplicationController
  def index
    render status: :forbidden
  end
end

Rubocop

ydakuka@yauhenid:~/Work/project$ bin/rails_docker rubocop -V

render status: 'forbidden' does not seem to be a valid argument compatible with the symbol argument, so it probably shouldn't be detected.
