error in code on tutorials/blogging page

I do not believe that the code `quarto install extension quarto-ext/video` is needed anymore on the https://nbdev.fast.ai/tutorials/blogging.html page. I think when they moved to Quarto version 1.2 they included [video](https://quarto.org/docs/authoring/videos.html) in the base Quarto program.

When I try to run the code, I get the following error:
`Extension not found in local or remote sources`

So my guess is they removed that extension from the extension library when they put it into the base Quarto program. I've tested the video capabilities with my version (1.2.335) and it works even though I wasn't able to install the video extension.
