Subject: [PATCH 53/61] Fix test suite for ruby 3.0 change for methods on
 subclass of Array

With ruby 3.0, especially with https://github.com/ruby/ruby/pull/3690 ,
for subclass of Array, `flatten` method now returns the instance of Array,
not of the subclass.

To keep the object instance of the subclass, use `flatten!` instead.
