Documentation Bug：the description of padding
Hi @PhyllisJi ,

Thanks for your time for reporting this related to `tf.keras.layers.ZeroPadding1D`. I have tested the code with dict as argument and it raises error.Attached [gist](https://colab.research.google.com/gist/SuryanarayanaY/3a88b01e5afd9b58d6d1aa55e7c35969/60839.ipynb) here for reference. 

Even in source code also there seems no implementation for dict as argument. I will made a thorough review before going for correcting the documentation. Thanks again for bringing this.
