Ionic Doc Demo Source link: 404

[fdambrosio]

A lot of Demo Source link in the Ionic Api Doc (for ex. Ionic Item) are wrong and it link to not found urls.
Example: https://ionicframework.com/docs/api/components/item/Item/
Demo source (under the smartphone emulator) link: https://github.com/ionic-team/ionic/tree/master/demos/src/item (404 not found)
