Rubocop identifies wrongly an scoped version of Exception

[vpereira]

Looks like the rule https://www.rubydoc.info/gems/rubocop/RuboCop/Cop/Lint/InheritException, doesn't take into account if the Exception class is scoped or not.

i.e

module DockerRegistry2
  class Exception < RuntimeError
  end

  class RegistryAuthenticationException < DockerRegistry2::Exception
  end
  # ...
end

Rubocop is however mixing this scoped DockerRegistry2::Exception class with ::Exceptions.
