Rubocop: Requiring both rubocop-rails and rubocop-performance in rubocop.yml throws warning

[RicardoTrindade]

---

Expected behavior

When requiring both rubocop-rails and rubocop-performance no warnings are thrown

Actual behavior

When running rubocop a warning is thrown .rubocop.yml:2: require is concealed by line 3

Steps to reproduce the problem

If you require both rubocop-rails and rubocop-performance in .rubocop.yml like this

require: rubocop-rails
require: rubocop-performance

It will throw a warning .rubocop.yml:2: require is concealed by line 3

RuboCop version

0.71.0

$ [bundle exec] rubocop -V
0.71.0 (using Parser 2.6.3.0, running on ruby 2.5.5 x86_64-linux)

Not sure if we should ignore the warning or update the config_loader.rb to ignore the require field on the .rubocop.yml
