genjavadoc is broken with Scala 2.13.13

[mdedetrich]

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.

fix merged; I'll roll a release soon — you can track that at #349
