* Fix the template in Getting Started to feature the latest version of jQuery, as per #14852
* Fix the modal documentation to mention the correct deprecation version (3.3.0 instead of the nonexistent 3.2.1).

1.11.1 is greater than 1.9.1 when compared via [SemVer](http://semver.org/), which #14852 basically does.
jQuery 1.9.1 is the minimum required version, but unless there's a jQuery-version-related bug in another library someone is using, there's no reason not to use to the latest 1.x jQuery, which is 1.11.1.
