Add `"Allowed"` to `Rails/HttpPositionalArguments`

[wscourge]

Is your feature request related to a problem? Please describe.

I have the following RSpec config:

RSpec.configure do |config|
  config.filter_run_excluding :broken, :flaky, :slow
end

and the following test:

RSpec.describe "api/v1/contacts" do
  path "/api/v1/contacts" do
    get "contacts", broken: true do # <===== HERE
      response(200, "successful") do
        schema oneOf: [{ "$ref" => "#/components/schemas/contacts" }]

        run_test! do |response|
          expect(response).to have_http_status :ok
        end
      end
    end

is a violation and gets autocorrected to get "contacts", params: { broken: true } do.

Describe the solution you'd like

I want .rubocop.yml to respect

Rails/HttpPositionalArguments:
  Enabled: true
  Allowed:
    - broken
    - flaky
    - slow

Describe alternatives you've considered

I just don't use it and have no better idea

Rails/HttpPositionalArguments:
  Enabled: false
