Remove save_state_warning in LambdaLR

[jsrozner]

Fixes #46405, #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)?

I updated the docstring in the local file (function level comments). Do I also need to edit somewhere else or recompile docstrings?

As mentioned in comment, the docstring will automatically regenerate the doc on master. :)

Also, though I didn't change any types here, how is typing (for IDE type checking) documentation generated / used)?

Since this is just updating the warning and the documentation, there is no need update the typing.

Yes, agreed. But I was curious how the pytorch library handles typing since it is not inlined in, e.g., these function definitions

Is anything else needed by me to finish this pull request?

We are migrating to inline, but the types are in *.pyi files adjacent :)

Thanks for signing and writing the pull request, this is good to go :)

That broke transformers where it's used:
https://github.com/huggingface/transformers/blob/aa0969c2f3cf5cf7ce5690e7b77f95b1622988d6/src/transformers/trainer_pt_utils.py#L37

But reading why it was done (goodness), transformers will just need to recode for this change.

Not sure how one could deprecate a constant...
