twirl is a sbt-plugin. sbt-plugins get published for Scala 2.12.
The 2.12.x scala compiler depends on 1.x versions for both scala-parser-combinators and scala-xml, see https://github.com/scala/scala/blob/2.12.x/versions.properties#L21-L22
If we would use 2.x versions, we would run into annoying dependency conflicts in sbt 1.5+
There is no need to upgrade these versions to 2.x, the only reason would be if we would cross build for Scala 3, but sbt-plugins do not need to be cross build for Scala 3.

See discussion in scala/scala#9743

add a .scala-steward.conf file to prevent the steward from attempting the upgrades?
