Upgrade Ruby to 3.4.1

Mainly for testing compatibility and getting ready to bump it whenever we are ready

You'll need to rebase this against latest master, since this is off an older commit with jekyll-4.3.4, which doesn't have the csv dep added.

So this currently fails with

6:33:13 PM: /opt/buildhome/.rvm/rubies/ruby-3.4.1/lib/ruby/3.4.0/bundled_gems.rb:82:in 'Kernel.require': cannot load such file -- csv (LoadError)

If i recall this correct i couldnt do it on github's webgui and because I'm away from laptop it might be much better to delete this branch and create a new PR
