[Saad Najmi (Saadnajmi)]

Please select one of the following

• I am removing an existing difference between facebook/react-native and microsoft/react-native-macos 👍
• I am cherry-picking a change from Facebook's react-native into microsoft/react-native-macos 👍
• I am making a fix / change for the macOS implementation of react-native
• I am making a change required for Microsoft usage of react-native

Summary:

In #2019 , we ifdefed out some props that were actually valid on visionOS, namely UIScrollViewContentInsetAdjustmentBehavior and UIScrollViewIndicatorStyle. Let's bring them back by adjusting the ifdefs

Changelog:

[VISIONOS] [FIXED] - Bring back missing ScrollView prop converters

Test Plan:

CI should pass. visionOS should compile locally.
