fix(@schematics/angular): replace interactive div with button in application component template

A keyboard user who has a problem in using a mouse, will not be able to select the `div`, because he cannot initiate the click event, which is specific to the mouse. Interactive elements like button can initiate the click event on keyboard events.

Instead of adding additional events, such as `keyup`, `keydown` or `keypress`, we replace these with a `button`.
