Remove save_state_warning in LambdaLR (#46813)
Summary:
Fixes https://github.com/pytorch/pytorch/issues/46405, https://github.com/pytorch/pytorch/issues/43352
I updated the docstring in the local file (function level comments). Do I also need to edit somewhere else or recompile docstrings?
Also, though I didn't change any types here, how is typing (for IDE type checking) documentation generated / used)?
