Subject: [PATCH] Drop Ruby 2.4 support and require RuboCop 1.13 or higher

RuboCop does not support Ruby 2.4 and rails/rails uses RuboCop 1.13.

- https://github.com/rubocop/rubocop/pull/9648
- https://github.com/rails/rails/commit/bbbc861

And https://github.com/toshimaru/rubocop-rails_config/pull/111 requires this PR.
Therefore, this PR drops support for Ruby 2.4 to enable the same cops as rails/rails.
