504 - Update to Ruby 3.3.1, update nokogiri, bundle update

[Janell-Huyck]

Fixes #504

• updated Ruby to new version 3.3.1 for security fix
• updated nokogiri, removing the pinning of versions
• deliberately pinned sqlite3 version since it was trying to use several different version with bundle install
• ran bundle update
• added instructions to circleci/config.yml file to add nvm and then use nvm to load node version 12.22.12, the current node version on the servers.
• updated one Pagy test because Pagy changed the way it creates/references class names.
