Auto Update Docs

[bobakfb]

Summary: This diff adds a python script update_docs.py which automatically generates torcheval.metrics.rst and torcheval.metrics.functional.rst, ensuring the API docs will always be in sync.

I also fixed several errors with the docstrings and missing imports which I found while writing this code.
