Test Ruby 4.0 previews

* As https://nodejs.org/api/os.html#oscpus says:
  os.cpus().length should not be used to calculate the amount of parallelism available to an application. Use os.availableParallelism() for this purpose.

-* Make sure you use the latest version with `- uses: ruby/setup-ruby@v1` (see https://github.com/ruby/setup-ruby/blob/master/README.md#versioning)
-* If the issue happens on JRuby or TruffleRuby, and does not happen on CRuby (please check), file an issue there instead. It's very unlikely ruby/setup-ruby is the cause.
-* Try to reproduce the issue locally by following the workflow steps (including all commands done by ruby/setup-ruby, except for `Downloading Ruby` & `Extracting Ruby`). If it does reproduce locally, it's not a ruby/setup-ruby issue.

-Please provide:
-* the code of or a link to the workflow used

-* the command and output of the step failing

+      First, take some time to think whether this is really an issue of ruby/setup-ruby and whether it is fixable in this action.
+      This action basically just downloads a prebuilt Ruby and adds it to `PATH`, so it is unlikely the bug is in this action.
+      Give some thoughts whether it could be an issue in your workflow, in the gems you use, in GitHub Actions, in Ruby, RubyGems, Bundler, etc.
+      This is NOT the place to ask help about your workflow failing (ask that on [GitHub Community](https://github.com/orgs/community/discussions/categories/actions) or [Discussions](https://github.com/ruby/setup-ruby/discussions) instead), it is only to report issues about ruby/setup-ruby.
