Fix building with Jekyll on Ruby 3.4 (#1079)

Ruby 3.4 removed several standard library packages, so they have
to be installed as gems instead.

This also updates Jekyll to use a version that's supported in Ruby 3.4.

The minimum required Ruby version is now 3.2.

+To localize the website, the `_i18n` folder contains translation files for each language. The default and fallback language is English `/_i18n/en.yml`.
 
 If you want to add a new language, create a new file in the `_i18n` folder with the language code as the filename and add the label for that language at `/assets/js/localize.js`. For example, for French, create `/_i18n/fr.yml` and add `'fr': 'Français'` in the `languageMap` const.
