Expected Behavior

I expected bundle exec jekyll serve --livereload to run without deprecation notice(s).

Current Behavior

Since I switched from Ruby 3.2.x to 3.3.0, bundle exec jekyll serve --livereload shows several deprecation notices, among them

warning: csv was loaded from the standard library, but will no longer be part of the default gems since Ruby 3.4.0. Add csv to your Gemfile or gemspec. Also contact author of jekyll-4.3.3 to add csv into its gemspec.
