[BUILD] Add Spark 4.x support to dev/reformat script

[slfan1989]

Summary

Add support for Spark 4.0 and Spark 4.1 to the dev/reformat script with automatic JDK and Scala version switching.

Changes

1. Fix Flink Maven profile (dev/reformat:55)

• Before: -Pflink,flink-1.18
• After: -Pflink-1.18
• Reason: Avoid activating non-existent flink profile

2. Add Spark 4.x support (dev/reformat:59-68)

• Add spark-4.0 and spark-4.1 to the version sweep list
• Auto-switch to scala-2.13 profile for Spark 4.x (Spark 4.x requires Scala 2.13)
• Auto-switch to JDK 17 for Spark 4.x (Spark 4.x requires JDK 17+)
• Auto-switch back to JDK 8 for Spark 3.x versions

3. Optimize Spark 3.5 coverage (dev/reformat:52)

• Remove spark-3.5 from the main sweep loop
• Keep it only in third-party build section to avoid duplicate formatting runs
• Third-party dependencies (Celeborn, Uniffle, Paimon, Flink, Iceberg) are still formatted with Spark 3.5

4. Update CI workflow (.github/workflows/style.yml)

• Add JDK 17 setup alongside existing JDK 8
• Enable style check to work with both Spark 3.x and Spark 4.x versions
