Review Comment:
for arrow-based UDFs, `sessionLocalTimeZone` is actually already passed to
the python side
https://github.com/apache/spark/blob/ed23cc39c32e0ca953f174f48ddff78ba24da375/sql/core/src/main/scala/org/apache/spark/sql/execution/python/ArrowPythonRunner.scala#L153
However this `workerConf` is not available in vanilla Python UDF, probably
we can consider supporting it in vanilla Python UDF in the future. also cc
