test-unit depends on power_assert that the recent versions require ruby 3.1 or later. While test-unit rescues syntax error at loading power_assert for old ruby versions, warnings for experimental features are not suppressed, and `assert_separately` fails because stderr is not empty, by default. Since adding `required_ruby_version` to power_assert causes the installation with old rubygems to fail, we just ignore warnings for experimental features totally.
