Extend explanation of `torch.cholesky_inverse` to consider batched inputs. (#69069)
Summary:
While implementing https://github.com/pytorch/pytorch/issues/68720,
We found out empirically that `torch.cholesky_inverse` support batched inputs, but it is not explained in doc: [link](https://github.com/pytorch/pytorch/pull/68720#pullrequestreview-817243697)
`torch.cholesky_inverse` is implemented in https://github.com/pytorch/pytorch/issues/50269 and the doc was updated at https://github.com/pytorch/pytorch/issues/31275 but not merged.
