Running an app under new ruby 3.3.2 that uses citeproc-ruby 2.0.0, results in this deprecation message in console:

warning: /Users/jrochkind/.rubies/ruby-3.3.2/lib/ruby/3.3.0/observer.rb was loaded from the standard library, but will no longer be part of the default gems since Ruby 3.4.0. Add observer to your Gemfile or gemspec. Also contact author of citeproc-ruby-2.0.0 to add observer into its gemspec.
