On https://docs.scala-lang.org/, Scala 2 appears before Scala 3, and on all Scala 3 documentation pages like https://docs.scala-lang.org/scala3/new-in-scala3.html there's a message warning that the documentation is a "Work in Progress". Now that Scala 3 is the default for new users and that we've had time to fix the documentation, I think we should remove the warning and display the Scala 3 doc first.
