docs/manual: Modify GitHub FOO_SITE explanation

GitHub has changed its layout, there is no longer any green nor grey
button, it's a link with a tiny icon that indicates if it's uploaded by
the maintainer or not.
In order to not confuse anyone, adding an image should make it clear.

 You can see on the release page if it's an uploaded tarball or a git tag:
 
-- If there is a green download button, like
-  https://github.com/zedshaw/mongrel2/releases/tag/v1.9.1[mongrel2], then it
-  was uploaded by the maintainer and you should use the link of that button to
-  specify +FOO_SITE+, and not use the 'github' helper.
-- If there is grey download button, like
-  https://github.com/xbmc/xbmc/releases/tag/13.2-Gotham[xbmc], then it's an
-  automatically generated tarball and you should use the 'github' helper
-  function.
