This was originally done on the master branch in
commit 03043839d5,
but never back-ported to 1.6.x.
That wasn't a big deal because docs.angularjs.org
served the master snapshot docs. However, now we
serve the 1.6.x snapshot docs, and it looks strange
that the official docs have the wrong branding :).
Bower was used to install multiple versions of jQuery which is now handled
using Yarn aliases. The remaining two packages, closure-compiler and
ng-closure-compiler were installed from zip files which is not supported by Yarn
(see https://github.com/yarnpkg/yarn/issues/1483); the first of them exists
on npm as the google-closure-compiler but only versions newer than we used are
published and they don't work with ng-closure-compiler so - instead - both were
checked in to the repository.
