README: Note that DisabledByDefault: true is useful for granularity

- Now that this behaviour has changed in `rubocop-github`, our users might want to have finer-grained control of which cops they enable since they can't rely on this gem to include that option now (if they even noticed).

 💭 Looking for `config/accessibility.yml` and the `GitHub/Accessibility` configs? They have been moved to [a new gem](https://github.com/github/rubocop-rails-accessibility).
 
+For more granular control over which of RuboCop's rules are enabled for your project, both from this gem and your own configs, consider using the `DisabledByDefault: true` option under `AllCops` in your project's `.rubocop.yml` file. This will disable all cops by default, and you can then explicitly enable the ones you want by setting `Enabled: true`. See [the RuboCop docs](https://docs.rubocop.org/rubocop/configuration.html#enabled) for more information.

 ### Legacy usage
 
 If you are using a rubocop version < 1.0.0, you can use rubocop-github version
