List The Running Ruby Version

The running Ruby version can be listed with the RUBY_VERSION constant.

For instance, if my Ruby version is 3.0.0, then I could get the version like so:

> RUBY_VERSION
=> "3.0.0"

This is nice if you just want to check in an IRB session or if you need it as part of a script.
