Bad symbolic reference to a Scala 2 symbol

Updating xml-interpolator to 0.18.1-RC1 is failing to load some symbol from scala-parser-combinators and scala-xml.

[error] Bad symbolic reference. A signature in /Users/nicolasstucki/.ivy2/cache/org.scala-lang.modules/scala-xml_2.12/bundles/scala-xml_2.12-1.2.0.jar(scala/xml/Null.class)

Note that it is trying to load the scala 2.12 version of those libraries. This might be related with the update to the 2.13 library in #7019. I would have expected the dependencies of scala-parser-combinators and scala-xml to be 2.13.

Actually the sbt-plugin needed an update
