Add ```react-native-screens``` native configs in Android during new app initialization

[I-am-Pritam-20]

Describe the Feature

Add react-native-screens native configs in Android as per described here : https://reactnavigation.org/docs/getting-started?framework=community-cli#installing-dependencies

Possible Implementations

• The native codes can be added right when a new app is initialized.
• For better performance with react-native-screens, as it is now a common part of all new @react-native-community/cli apps , so the native codes should already be there rather adding manually.
