Fixes #27043 - Make rubocop work again

The behavior of include changed in rubocop 0.56.0[1] and it started
overriding defaults provided by rubocop completely. This lead to only
rabl and rake files being checked by rubocop.

All of the file types which were manually included are being checked by
rubocop by default now and there's no need to keep them around.
