docs(tutorial): Update step_12.ngdoc

[elwinarens]

1. The example includes the wrong version of jQuery, if the version notification is still correct and up-to-date.
2. If jQuery 1.10.x must be used, then i think it's important to move the version alert up to below the example of the app/index.html, instead of way down below the fold.
