docs: Fixed docstring indentation for documentation (#37739)
Summary:
Hello there,
I was going through the default initialization of some layers, and ended up on the `torch.nn.init` documentation. As shown below, there was a slight issue with the docstrings of both `kaiming_normal_` and `kaiming_uniform_` that yielded a wrong list of function parameters:

This PR fixes the indentation in the corresponding docstrings.
Any feedback is welcome!
