Scaladoc documentation on external mappings

[charpov]

The Scaladoc documentation (https://docs.scala-lang.org/scala3/guides/scaladoc/settings.html) states:

Example external mapping is: -external-mappings:.*scala.*::scaladoc3::https://scala-lang.org/api/3.x/,.*java.*::javadoc::https://docs.oracle.com/javase/8/docs/api/

It seems that some slashes are missing and it should read:

Example external mapping is: -external-mappings:.*scala/.*::scaladoc3::https://scala-lang.org/api/3.x/,.*java/.*::javadoc::https://docs.oracle.com/javase/8/docs/api/
