Tests don't work for 2.4.1

When trying to build 2.4.1 (after removing the now unneeded patch and the simplecov cleanup code) I get this:

A new release of RubyGems is available: 3.6.7 → 3.6.8!
Run `gem update --system 3.6.8` to update your installation.

removed 'tmp_install/usr/lib/ruby/gems/3.4.0/cache/rubyzip-2.4.1.gem'
removed directory 'tmp_install/usr/lib/ruby/gems/3.4.0/cache/'
