mistakes in the documentation of the ProgressBar

I believe the are some mistakes in this documentation: https://developer.garmin.com/connect-iq/api-docs/Toybox/WatchUi/ProgressBar.html

In multiple places it mentions `Ui.` but I think it should be `WatchUi`

e.g.

1. class MyProgressDelegate extends Ui.BehaviorDelegate
2. class MyBehaviorDelegate extends Ui.BehaviorDelegate
3. Ui.pushView
4. Ui.SLIDE_DOWN
