描述

I know that it's possible to define our own custom Differentiable Optimizers and get higher to register them. But I was wondering why optim.AdamW is not supported, since from the doc it appears that optimizers from torch.optim are available out of the box.

研究方向
Investigate how existing optimizers like SGD and Adam are registered in higher's source code (e.g., in `higher/optim.py`). Add `torch.optim.AdamW` by following the same pattern, ensuring weight decay and other parameters are correctly handled. Check if there are any existing tests for optimizer support and add a test for AdamW.
