[TorchScript] Fix archive file extension in tutorials (#1310)

SplitInfinity · web-flow · commit e72255a40883 · 2021-01-19T09:49:10.000-05:00
**Summary**
Tutorials, documentation and comments are not consistent with the file
extension they use for JIT archives. This commit modifies certain
instances of `*.pth` in `torch.jit.save` calls with `*.pt`.
    
**Test Plan**
Continuous integration.
    
**Fixes**
This commit fixes #49660 in the pytorch/pytorch repository.
