### What changes were proposed in this pull request? This PR simplifies the `getSerializationProxy` function in the `IndylambdaScalaClosures`. The main change is to remove the `isClosureCandidate` check when determining if a class is a closure because Apache Spark 4.0 no longer support Scala 2.11. ### Why are the changes needed? The reason for removing the `isClosureCandidate` check is that in Scala 2.12 and later versions, closures are implemented as synthetic classes generated by the Java LambdaMetafactory. These synthetic classes do not need to implement the `scala.Function` interface, which is what the `isClosureCandidate` check was originally checking for. Therefore, the `isClosureCandidate` check is not necessary for identifying closures in Scala 2.12 and later versions. ### Does this PR introduce _any_ user-facing change?
