Subject: [PATCH] Test with Ruby 4.0

I added Ruby 4.0 to the CI matrix.

Cleaning up: Use v6 of actions/checkout, and let ruby/setup-ruby handle
the installation and caching of gems. Quotes around the "3.0" ruby
version makes sure GitHub Actions don't convert it from float to integer
meaning we were using the latest v3.x...

Using shorthand Yaml array syntax, and I fixed the latest date in the
changelog.
