[SPARK-16651][PYSPARK][DOC] Make `withColumnRenamed/drop` description more consistent with Scala API ## What changes were proposed in this pull request? `withColumnRenamed` and `drop` is a no-op if the given column name does not exists. Python documentation also describe that, but this PR adds more explicit line consistently with Scala to reduce the ambiguity. ## How was this patch tested? It's about docs. Author: Dongjoon Hyun <dongj...@apache.org> Closes #14288 from dongjoon-hyun/SPARK-16651.
