fix: header config missing ref (#2434)

## Description

This PR changes `ScreenStackHeaderConfig` into a
[forwardRef](@alduzy/reanimated-patch).

This is needed if you want to attach `ref` to it, which
**react-native-reanimated** needs to do
[here](https://github.com/software-mansion/react-native-reanimated/blob/1d417a5c711d60822d25bd8b823f1f5968214bde/apps/common-app/src/examples/ScreenStackHeaderConfigBackgroundColorExample.tsx#L24)
in order to migrate to v4, since the header config is now a function
component and cannot be used directly anymore.

Without this change the app crashes with `Cannot read property
'getScrollableNode' of null`.
