Update Ruby to 3.4

This gets us on the latest 3.x series of Ruby. Some minor performance
benefits for building, but the main advantage is this version isn't EOL
so it's easy to install for anyone to build the site locally.

We need to update Jekyll in coordination since there were a few default
gem changes and other minor updates.
