Issue: [functorch] colab links on functorch 0.2.0 website should be linked to a permalinked version of the colabs
Labels: module: docs,triaged,module: functorch

### 🐛 Describe the bug

Visit the AOT Autograd tutorial at:  https://pytorch.org/functorch/stable/notebooks/aot_autograd_optimizations.html
Click the colab icon so you can run the tutorial...it's linking to a colab dir that no longer exists in the repo, so you'll
receive:
~~~
Notebook not found
There was an error loading this notebook. Ensure that the file is accessible and try again.
Ensure that you have permission to view this notebook in GitHub and authorize Colaboratory to use the GitHub API.

The notebook can be loaded into colab by going to the jupyter notebook in github, and then clicking the colab button there..  (albeit with an odd run in colab icon still showing even in colab) but a typical user will not want to go figure out the correct steps and path to run:
