### What changes were proposed in this pull request? This PR aims to make Scala 2.13 the default Scala version in Apache Spark 3.5. ### Why are the changes needed? The current releases of Scala community are `Scala 3.2.2` and `Scala 2.13.10`. - https://scala-lang.org/download/all.html Although the Apache Spark community has been using Scala 2.12 by default since Apache Spark 3.0 and Scala community will release Scala 2.12.18 for Java 21 support, we had better focus on `Scala 2.13+` more from Apache Spark 3.5 timeline to adopt Scala community's activity. Since SPARK-25075 added Scala 2.13 at Apache Spark 3.2.0, the Apache Spark community has been using it as a second Scala version. This PR aims to switch only the default Scala version from 2.12 to 2.13. Apache Spark will support both Scala 2.12 and 2.13 still. ### Does this PR introduce _any_ user-facing change? Yes, but we still have Scala 2.12. ### How was this patch tested? Pass the CIs. Closes apache#41344 from dongjoon-hyun/SPARK-43836.
