npm install fails after creating a fresh library

Description

After running create-react-native-library, when trying to call npm install either in the module folder or the generated example folder, I get the following error:

The issue occurs because create-react-native-library sets react@19.0.0 but does not update @types/react and other dependencies accordingly. This causes installation errors when users run npm install in the generated project.

Solution
The package.json in the template should be updated to explicitly set @types/react@19.0.0 (and any other related dependencies) to match the react version. This will ensure all users get the correct versions when generating a new React Native library.

Let me know if this can be updated in the template!
