EasyKeeper v2.0.0: Migration to Cloud

This release introduces the integration of Firebase Firestore as the new data storage mechanism, replacing the previous usage of local storage. With Firestore, the application benefits from a scalable and reliable cloud-based database for storing and retrieving user data.

In addition, this release includes the implementation of a login feature, allowing users to authenticate and securely access the application's features. Users can now sign in using their Google accounts and enjoy personalized note management functionality.
