docs(tutorial): correct spelling mistake
fix(version-info): explicitly specify the remote

`git ls-remote --tags` assumes that you have a remote set up for your
current branch.  That isn't the case, at least for me, when I'm working
on local branches.  `grunt write` doesn't do the right thing in that
case (`git ls-remote --tags` bails out and the silent: true param makes
this a pain to debug.)  Prefer explicit to implicit.

Closes #6678.
chore(release): fix angularjs.org cdn script
test($rootScope): add assertion to test ensuring that NaN -> NaN does not throw

https://github.com/angular/angular.js/commit/fb6062fb9d83545730b993e94ac7482ffd43a62c implements a
fix for NaN values causing $watchCollection to throw an infdig error. This change updates the test
by adding an assertion which explains what is actually being tested a bit better, and may also
provide better information in the event that the test ever fails.
