Empty scaffolding fails rubocop

[rubys]

Empty scaffolding produces code that doesn't conform to rubocop-rails-omakase requirements.

While empty scaffolding may seem odd, it is not unusual to have an object like a Cart which has a relationship with Products through a LineItems relationship object.

Steps to reproduce

Since rails new --edge may pick up 7.1, I've provided reproduction instructions in the form of a dockerfile:

FROM ruby:3.3.3-slim

RUN apt-get update -qq && \
    apt-get install -y build-essential git

RUN gem install rails -v 7.2.0.beta2 --pre

RUN rails new demo

WORKDIR demo

RUN bin/rails generate scaffold Cart

RUN rubocop

CMD sleep infinity

Expected behavior

38 files inspected, no offenses detected

Actual behavior
