Subject: [PATCH] Fix missing type for login-password alert prompt (#49757)

Summary:
When using the `login-password` prompt type, there is a TypeScript type mismatch issue. The `callbackOrButtons` parameter returns an object with `{login: string, password: string}` structure, but this type variation is not properly included in the **AlertType** type definition. This causes TypeScript to show type errors when using callback functions that expect credentials in the format `(credentials: {login: string, password: string}) => void`.

## Changelog:
- [General] [Fixed] Add missing type variation `{login: string, password: string}` to **AlertType** type definition to properly support `login-password` prompt callbacks

Pull Request resolved: https://github.com/facebook/react-native/pull/49757

Test Plan: This change is purely type-related and doesn't affect runtime behavior.
