This commit fixes the following error when using `rubocop:auto_correct`
deprecated custom rake task.

```console
% bundle exec rake lint:rubocop:auto_correct
rake aborted!
NoMethodError: undefined method `Rainbow' for
#<RuboCop::RakeTask:0x000000010b7a9020 @name=:rubocop, @verbose=true,
@fail_on_error=true, @patterns=[], @requires=[], @options=[], @formatters=[]>

          warn Rainbow(
               ^^^^^^^
```

And it fixes the following error that occur after that.

```console
% bundle exec rake lint:rubocop:auto_correct
rubocop:auto_correct task is deprecated; use rubocop:autocorrect task or
rubocop:autocorrect_all task instead.
