Add a link to this repo to https://deps.dev/about (or in the footers)

I'd started to drop y'all an email when I remembered that this repo was here - it'd be great to get a link to the repo discoverable on the site, if possible!

Good idea, thanks! I've added a link in the footer of deps.dev and blog.deps.dev. We're also working on further restructuring of our docs to make things a bit more discoverable. 😊
