Docs Typo: URL Points to Archived Repo

Hello there!

Very quick nitpick: When viewing this awesome about page:
* https://fastht.ml/about/

And when viewing this line:

> Here is the [source code](https://github.com/AnswerDotAI/fh-about/blob/main/overview.py) for the current page, for instance. You'll see that the code is very simple, relying on Python components like Markdown to build the page. The components are simple Python functions---here is the [source code for Markdown](https://github.com/AnswerDotAI/fh-about/blob/main/app.py#L6),

I see that they point to the archived `AnswerDotAI/fh-about` repo, so could we change the two links above with these respectively?:

* https://github.com/AnswerDotAI/home-fasthtml/blob/main/about/overview.py
* https://github.com/AnswerDotAI/home-fasthtml/blob/main/about/app.py

Nevertheless, phenomenal repo idea and execution! 🙌

#StayChill

Inspect the about page source around the two links mentioned in the issue, including about/overview.py and about/app.py. Replace the archived AnswerDotAI/fh-about URLs with the corresponding home-fasthtml URLs provided, then verify both links resolve to the current repository.
