refactor: rename automatic -> auto enums type values to align between platforms - #3328

Description

This PR aligns property naming in "gamma" components between platforms. Indeed it does not make sense to have part of the enum values called auto and part automatic, e.g. TabBarMinimizeBehavior::automatic & TabBarItemLabelVisibilityMode::auto.
Since these are new APIs we can have it nicely aligned on stable release.

I've decided to go with auto in favour of automatic because it is shorter and clearly conveys the meaning.

To be honest I can't decide. There is no consistency neither in the world nor in our API.
I've done a quick research and we have in react-native-screens:

• TabBarItemLabelVisibilityMode::auto (Android, not-yet-stable API)
• ScreenProps::statusBarStyle::auto (Android, iOS, stable API)
• TabBarControllerMode::automatic (iOS, not-yet-stable API)
• TabBarMinimizeBehavior::automatic (iOS, not-yet-stable API)
• ScrollEdgeEffect::automatic (iOS, stable API)
• SearchBarPlacement::automatic (iOS, stable API)
• SplitBehavior::automatic (iOS, not-yet-stable API)
• SplitDisplayMode::automatic (iOS, not-yet-stable API)
• SplitDisplayModeButtonVisibility::automatic (iOS, not-yet-stable API)

Then in react-native:

• ScrollView::overScrollMode::auto (Android, RN API)
• Image::resizeMethod::auto (Android, RN API)
• TextInput::importantForAutoFill::auto (Android, RN API)
• View::importantForAccessibility::auto (Android, RN API)
• View::pointerEvents::auto (RN API)
• All the layout props in RN use auto
• All the test style props in RN use auto
• All the view style props in RN use auto
• ScrollView::contentInsetAdjustmentBehavior::automatic (ScrollView public API)

Additionally many iOS props such as ScrollView::automaticallyAdjustContentInsets use the automatic.

The dividing line here is clearly the platform.
And it seems that the convention in react-native is to stick to the platform conventions.
