inconsistency between tutorial notebook and resnet model

[bulaienTang]

Describe the bug "upsampling" removed in resnet kwargs but still being passed in NeurIPS2022_CCAI_Tutorial.ipynb

To Reproduce run the downscaling section of NeurIPS2022_CCAI_Tutorial.ipynb

Expected behavior the model should not accept "upsampling" as a parameter

Please remove the upsampling parameter in the notebook, as it is no longer required. Detailed explanation here: https://github.com/aditya-grover/climate-learn/pull/44#issuecomment-1416638937

[bulaienTang]

Done.
