genjavadoc is broken with Scala 2.13.13

It seems that with the latest Scala 2.13.13 release genjavadoc is broken (we are currently experiencing this in Pekko). This is the error we are getting

To reproduce run

 sbt -Dpekko.genjavadoc.enabled=true "docs/paradox; unidoc"

in https://github.com/apache/incubator-pekko-http and make sure that https://github.com/apache/incubator-pekko-http/blob/main/project/Dependencies.scala#L37 is set to 2.13.13, note that 2.13.12 works fine. Also note that the newly release 2.12.19 is working without issues.
