# Your RubyGems version (3.0.3)) has a bug that prevents `required_ruby_version` from working for
# Bundler. Any scripts that use `gem install bundler` will break as soon as Bundler drops support
# for your Ruby version. Please upgrade RubyGems to avoid future breakage and silence this warning
# by running `gem update --system 3.2.3`
