Add the website to the GitHub "About" section

[justinmc]

Would it make sense to add the link to the website (https://flutter.github.io/samples/) to the About section @domesticmouse? Usually I look for links like that there and was surprised to not see it. There should be a gear icon in the About section of the main repo page that reveals a "website" field.

I think this makes sense. @johnpryan, WDYT?

SGTM

We could also consider creating subdomain like samples.flutter.dev

Un-assigning myself since I can't edit the sidebar.

@Hixie could you add a link to "https://flutter.github.io/samples/" to the sidebar here?

I checked "Use your GitHub Pages website".

Looks great, thanks!
