fix: Update broken repo hyperlink

[lamhoangtung]

Description

Hi, I'm looking in the new documentation over at https://pytorch.org/TensorRT/ and found some hyperlink broken for the torchtrt_runtime example and decided to do a quick PR to fix it.

I also found a bunch of old link to this repo and updated it with the new repo link under pytorch organization

Can you drop changes to //docs from this PR? Our CI will build a new version once its checked into master and it will make this PR much easier to review.

[lamhoangtung]

Sure @narendasan. I just drop all changes to the docs directory.

[narendasan]

Hmm the docs changes are still around, can you drop any changes to docs and rebase on master? Or tt might be easier to do this on a new branch and open a new PR

[lamhoangtung]

@narendasan. Seems like the changes to docs are autogenerated. Sure. Let me open a new PR
