license header check has problems with deleted files

[revans2]

A lot of recent builds have been failing with license header checks that are "wrong" but many if the files listed are files that were deleted.

--------- RESULT ---------
Following files missed copyright/license header or expired:
sql-plugin/src/main/scala/com/nvidia/spark/rapids/AlluxioCfgUtils.scala
sql-plugin/src/main/scala/com/nvidia/spark/rapids/AlluxioConfigReader.scala
sql-plugin/src/main/scala/com/nvidia/spark/rapids/AlluxioFS.scala
sql-plugin/src/main/scala/com/nvidia/spark/rapids/AlluxioUtils.scala
sql-plugin/src/main/scala/org/apache/spark/sql/execution/datasources/rapids/GpuPartitioningUtils.scala
sql-plugin/src/main/spark320/scala/org/apache/spark/sql/types/shims/PartitionValueCastShims.scala
sql-plugin/src/main/spark330/scala/org/apache/spark/sql/types/shims/PartitionValueCastShims.scala
sql-plugin/src/test/scala/com/nvidia/spark/rapids/AlluxioConfigReaderSuite.scala
sql-plugin/src/test/scala/com/nvidia/spark/rapids/AlluxioUtilsSuite.scala
sql-plugin/src/main/spark320/scala/com/nvidia/spark/rapids/shims/FileIndexOptionsShims.scala
sql-plugin/src/main/spark332db/scala/com/nvidia/spark/rapids/shims/FileIndexOptionsShims.scala

All of those files were deleted from the repo and cannot have a copyright that was updated.

Hi @revans2, the cause of the failure is the workflow compared commit of feature branch and an very old commit of target branch. That's because the feature branch has not done an upmerge for a long time, it missed some recent commits of target branch. In your example, the unexpected files are deleted in these missed commits.

Actually we have a reminder in the log https://github.com/NVIDIA/spark-rapids/actions/runs/12824629012/job/35761088887#step:4:440 .

If there are files that are not modified by your PR, please try upmerge first.

Let me try to make the reminder more noticeable to avoid missing it.
