Support Scala 2.13

Hi 👋 ,

For v2.0.0 release, it is stated "Future proof for Spark 4.0 / Scala 2.13 / JDK 17" however, official binaries built for Scala 2.13 Spark 3 do not appear to be published publicly on Maven Central or Maven repositories. Is it possible to publish or create the Scala `2.13` binaries please?
