[BUG] - Spark_Events_Bronze - taskEndReason.StackTrace
When there are no spark events with a task failure the default return type for taskEndReason.StackTrace is String as it's implicitly cast to string in the ingest dataset since all are null string. This needs to be forced to a struct to ensure it can be merged even when all values are null.
depends on #503 -- once 503 is completed this can be added to min schema but not before as it is an array of struct
merged with #649
