Fix FlatList type (#3029)

## Description

Closes
#2990

Removes `renderScrollComponent` from the public API of FlatList exported
by Gesture Handler, as its being overwritten with Gesture Handler's
scroll view anyway.

## Test plan

Verify that `renderScrollComponent` causes a TypeScript error on
FlatList exported from RNGH.
