Subject: [ruby/pp] Support private instance_variables_to_inspect
 (https://github.com/ruby/pp/pull/70)

* Support private instance_variables_to_inspect in pp

Ruby supports calling instance_variables_to_inspect even when
it is defined as a private method (ruby/ruby#13555).

This change aligns pp with Ruby's behavior.
