Change name for namedtuple return of torch.linalg.svd (#57181)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/57181
Documentation for torch.linalg.svd says:
> The returned decomposition is a named tuple `(U, S, Vh)`
The documentation is correct while the implementation was wrong.
Renamed `V` -> `Vh`. `h` stands for hermitian.
This is a BC-breaking change but our linalg module is beta, therefore we can do it without a deprecation notice or aliases.
