Update SBT, Scala.js, Scala Native, and plugins

My understanding is that this should be enough for publishing as long as the credentials in this repo have been rotate since the Central Portal migratio.

Thanks @keynmol! But with the sbt update there are some changes with the way all the cross versions are set up. That's where the work actually is, and I didn't have time to dig into.

I am assuming that SBT 1.7.0 is the one introducing changes to how cross versions work:

https://github.com/sbt/sbt/releases/tag/v1.7.0

. In sbt 1.7.0, a concrete version such as ++ 3.0.1 requires exact version to be present in crossScalaVersion.

Which is in contrast with the way runtime and reporter are set up in this project.

I added a couple of hacks to see how the tests go (they pass locally), but we can think of an actual fix
