Subject: [PATCH] Remove deprecated Instance type aliases (Flow)

Summary:
Remove the deprecated `PublicScrollViewInstance` and `PublicModalInstance` type aliases, replacing all remaining usages with the canonical `ScrollViewElement` and `ModalElement` types.

NOTE: Existing equivalent types are **left alone** in the manual `.d.ts` sources (current TS API), as this is covered by the existing breaking migration notes for ref types under the Strict API.

**Changes**

- Delete `PublicScrollViewInstance` alias (ScrollView.js)
- Delete `PublicModalInstance` alias (Modal.js)
- Update `IntersectionObserverExplicitRootScroll.js` rn-tester example

Changelog: [Internal]
