### What is this PR for? This PR updates `SparkInterpreterLauncher` to throw `IllegalArgumentException` when the Scala version parsed from `spark-submit --version` is outside the supported range. Unsupported Scala versions are invalid input values for this validation path, so `IllegalArgumentException` better describes the failure than a generic `Exception`. The exception message is intentionally unchanged, and the `detectSparkScalaVersion(...)` method signature still declares `throws Exception` because the method can still raise checked exceptions from process execution, stream reading, and fallback Scala version detection. This is behavior-preserving for callers: the existing caller catches `Exception` and wraps it in an `IOException`, so the surfaced behavior and public API remain unchanged. ### What type of PR is it?
