Ensure Gesture Nav Edu animation scales to fit different screen sizes

Browse Source 
The lottie animation in the gesture nav tutorial wasn't scaling correctly for certain devices
leading to gaps around the animation. This change uses animation's scale transformation to ensure it fits the
dimensions of the device.

Flag: ENABLE_NEW_GESTURE_NAV_TUTORIAL
Fix: 295809541
Test: Went through the tutorial on different types of devices and ensure
the animation takes up the entire screen.
