feat: enable screens by default

[WoLewicki]

Description

Enabled native components of react-native-screens by default. It results in no need of calling enableScreens() at the top of your app to use them 🎉

Changes

Changed index.native.tsx.

Test code and steps to reproduce

Do not call enableScreens() at the top of your app and spot that native components are used.

Checklist

• Ensured that CI passes

Is it still possible to disable it, even though it's being enabled by default?

[kacperkapusciak]

@yanush add these lines to entry file of your app:

import { enableScreens } from 'react-native-screens';

enableScreens(false);
