Update TS docs for contentInsetAdjustmentBehavior

[steinalex]

Summary:

Update the TS docs to reflect the default value for contentInsetAdjustmentBehavior. The TS docs suggest it will be automatic however it's actually never.

The default behaviour is correctly specified in the JS docs:

react-native/packages/react-native/Libraries/Components/ScrollView/ScrollView.js

Line 306 in 850760a

* "never". Available on iOS 11 and later.

It's also documented as the default in the native module: https://github.com/facebook/react-native/blob/main/packages/react-native/React/Fabric/Mounting/ComponentViews/ScrollView/RCTEnhancedScrollView.mm#L34

Changelog:

[General] [Fixed] - Fix TS docs for contentInsetAdjustmentBehavior

Thanks @steinalex for this PR -- just wondering why never is the default when https://developer.apple.com/documentation/uikit/uiscrollview/contentinsetadjustmentbehavior-swift.property mentions it is automatic. I'm not familiar with why there is conflicting information. Could you expand?

[steinalex]

Hey @lunaleaps! I was a bit confused by the iOS docs too, but I assumed it must be never by default after fixing a navigation bug.

Take a look at this Expo snack and run it on iOS. If you go to the ScrollView and remove contentInsetAdjustmentBehavior or set it to contentInsetAdjustmentBehavior="never" it has the same effect (the first few elements are hidden behind the large title). Only once it's set to automatic does the bug resolve, which made me assume it's default is never.

Sorry I don't have anything more comprehensive than that, at the moment.

[steinalex]

It was defaulted to never in this PR, if that helps: 9b059b6

[lunaleaps]

Ah I see, so maybe its a react-native specific default. Gotcha, thanks for answering!

Current versions of RN don't support anything before 13.4, or maybe even 15, so this could just be removed.

[steinalex]

Thanks for the feedback @NickGerleman! I've updated both the JS and TS documentation to remove the iOS specific version part
