Scala 3 upgrade

[ddugovic]

Scala 3 documentation is still a work in progress, however the language was released and in theory is supposed to be easier for new developers to understand than Scala 2 is:

We have to wait for our dependencies to be upgraded first

Hi Ornicar! for what I see, you did port to scala 3, but with many acrobatics with Play and reactiveMongo. I'm myself trying to port my scala2 project to scala3, and trying to get rid of the new license of Akka and ReactiveMongo. I've seen that you are also active on the Pekko project, so could you tell me what are you advancement to use only scala3 libraries with just apache licenses? isn't it too soon to dump Akka for Pekko?
PS: I admire all the story about lichess! what an adventure! Tremendous job, and what a result!
