Workaround for rubocop-rspec_rails 2.28

The fix for #12836 will be improved.
This issue is related to the development dependency rubocop-rspec_rails,
and modifying RuboCop's production code was not appropriate.
The version will be locked in the Gemfile until a correction can be made to rubocop-rspec_rails.
