Fixes doc errors in `Tensor.triu()`, `Tensor.tril()`, `Tensor.ravel()`. (#71057)
Summary:
Hi, PyTorch Team!
I am very much interested in starting up my contribution to PyTorch. I made several contributions in NumPy and CuPy, but this is my first PR towards PyTorch. I aim to contribute more in the upcoming future.
The PR fixes https://github.com/pytorch/pytorch/issues/70972 https://github.com/pytorch/pytorch/issues/70975.
#### Aim of PR
The functions like `Tensor.ravel`, `Tensor.tril`, `Tensor.tril_`, `Tensor.triu`, and `Tensor.triu_` had a couple of typos in docs. The PR aims to resolve that.
I'm looking forward to your viewpoints. Thanks!
