feature failure against Ruby head

[faisal]

#492 and #493 both fail in the same place when testing against HEAD:

expected `rubycritic --version  --no-browser` to have output "RubyCritic 4.9.1\n"
but was:
   RubyCritic 4.9.1

   /home/runner/work/rubycritic/rubycritic/vendor/bundle/ruby/3.4.0+0/gems/childprocess-5.0.0/lib/childprocess.rb:7: warning: logger was loaded from the standard library, but will no longer be part of the default gems since Ruby 3.5.0. Add logger to your Gemfile or gemspec.

This feature is not related to any codepaths touched by the PRs (particularly the case of #493, which touched no code paths).

This reproduces locally. The feature patch is trivial but I'm trying to figure out why the behavior changed against HEAD.
