docs(overview): correct the input validation example

The documentation says that the input should be red if you enter

input type to number and adds an ng-pattern to ensure that the number
is an integer.

 From the `ng-model` attribute of the `<input>` tags, Angular automatically sets up two-way data
 binding, and we also demonstrate some easy input validation:

+    Quantity: <input type="number" ng-pattern="/\d+/" step="1" min="0" ng-model="qty" required >
