Summary:
iOS 13 added a new property to `UIScrollView`: `automaticallyAdjustsScrollIndicatorInsets`, which is `YES` by default. The property changes the meaning of the `scrollIndicatorInsets` property. When `YES`, any such insets are **in addition to** whatever insets would be applied by the device's safe area. When `NO`, the iOS <13 behavior is restored, which is for such insets to not account for safe area.
In other words, this effects ScrollViews that underlay the device's safe area (i.e. under the notch). When `YES`, the OS "automatically" insets the scroll indicators, when `NO` it does not.
There are two problems with the default `YES` setting:
1. It means applying `scrollIndicatorInsets` to a `ScrollView` has a different effect on iOS 13 versus iOS 12.
2. It limits developers' control over `scrollIndicatorInsets`. Since negative insets are not supported, if the insets the OS chooses are too large for your app, you cannot fix it.
Further explanation & sample code is available in issue https://github.com/facebook/react-native/issues/28140 .
This change sets the default for this property to `NO`, making the behavior consistent across iOS versions, and allowing developers full control.

Test Plan:
Updated the RNTester example to explain what to expect. Also removed the `pageScreen` modal example for now as mentioned in my Github comment.

Here are screenshots of the demo app (from the original bug) before (with safe area applied to insets) & after (without safe area applied to insets):

Summary:
Changelog: [internal]
Default value for `snapToEnd` and `snapToStart` was incorrect in Fabric. This makes no practical difference as default value is never used (JavaScript always sets true or false).
Default value of `snapToEnd` is true.

Default value of `snapToStart` is true.
