Docs: `overrideScrollViewContentInsetAdjustmentBehavior` option missing from Native Bottom Tab Navigator page

The Tab.Screen option overrideScrollViewContentInsetAdjustmentBehavior is implemented and exposed in @react-navigation/bottom-tabs/unstable but not listed on the Native Bottom Tab Navigator docs page.

It's an iOS-only option with non-obvious default behaviour, and it's the only escape hatch for a fairly common visible bug — a blank gap appearing above content in a native-stack screen with headerTransparent: true nested inside a NativeTabs tab. The bug was reported in #12946 and the fix is exactly this option, but a reader hitting the symptom has no way to discover it from the docs.

JSDoc from the source

Whether to override the contentInsetAdjustmentBehavior of the first ScrollView in the first descendant chain from the tab screen.

By default, react-native's ScrollView has contentInsetAdjustmentBehavior set to never instead of UIKit-default (which is automatic). This prevents ScrollViews from respecting navigation bar insets. When this prop is set to true, automatic behavior is reverted.

To disable this behavior for specific screens, set this option to false.

Only supported with native implementation.

Defaults to true. iOS-only.

Suggested doc placement

Under "Options" on docs/native-bottom-tab-navigator.md, next to tabBarStyle / tabBarMinimizeBehavior (other iOS-flavoured presentation options). A brief mention of the symptom it fixes ("blank gap above content in a nested transparent-header screen on iOS") would help a lot.

Happy to PR if useful — just want to flag the gap before the next person hits it.

開啟 docs/native-bottom-tab-navigator.md，閱讀 tabBarStyle 和 tabBarMinimizeBehavior 附近的 Options 區段。檢查 packages/bottom-tabs/src/unstable/types.tsx 中該選項的 JSDoc，然後記錄其預設值、iOS-only 和 native-only 限制，以及透明標頭出現空白間隙的現象。當讀者可以在 Native Bottom Tab Navigator 頁面上找到並理解此選項時，即表示完成。
