Finish migrating to Ruby 3.3.0

As the comment in `deploy.yml` explains, this was a multi-step process,
but it went very smoothly as planned, hooray!!

I noticed again while making this change that Bundler doesn't seem to
be availing itself of the checked-in dependencies in `vendor/cache`. I
think I know the fix for this, I'll toss it into an upcoming change and
see if it works!
