feat: keepAliveRiverpod shorthand

[Zfinix]

When using Riverpod for state management in Flutter, it is essential to ensure that your code is efficient and easy to read. One way to improve the readability and brevity of your code is to use a shorthand annotation, @keepAliveRiverpod, instead of @Riverpod(keepAlive: true).

The @keepAliveRiverpod annotation is a concise way to indicate that a provider should remain active even when not being listened to. It is a simple and clear declaration that is easy to understand and write:

@keepAliveRiverpod
final myProvider = Provider((ref) => MyService());

Using @keepAliveRiverpod makes the intention of your code immediately clear to anyone who is reading it. It is more intuitive than the @Riverpod parameter and can be easily identified. So, by using @keepAliveRiverpod, you can improve the readability and brevity of your code.

Oh my bad, all right I did not know about that step first.
