What changes were proposed in this pull request?
Before Spark 4.0, Scala 2.12 was primary and Scala 2.13 was secondary. The release scripts build more packages (hadoop3, without-hadoop, pyspark, sparkr) for the primary Scala version but only one package for the secondary. However, Spark 4.0 removes Scala 2.12 support and the release script needs to be updated accordingly.
