Add link to napari docs website in this repository

[cnstt]

🧰 Task

Maybe it would be nice to add a link to this github repo, showing where this documentation is actually deployed, maybe this: https://napari.org/dev/index.html .

I think explaining that merged PRs get deployed to dev and then once a napari release is cut, then they become part of the stable docs makes sense.

I think @cnstt is actually suggesting adding a link to the website in the README or the repo settings - looks like we forgot it, so both ideas seem good to me!

I've added to repo settings. Will probably make a PR for the README soon (unless @cnstt would like to) We can combine Peter and Melissa's ideas, there
