Additional Getter Methods For Retrieving User Information

[jeramyhing]

Description

This PR updates the Laravel\Socialite\AbstractUser and Laravel\Socialite\Two\User classes to add additional getter methods. It also enhances the existing tests to verify that the new getter methods return the correct property values.

Changes

AbstractUser Class Updates

New Getter Method:

• getAttributes: Get the user's attributes.

Two\User Class Updates:

New Getter Methods:

• getToken: Retrieves the user's access token.
• getRefreshToken: Retrieves the user's refresh token.
• getExpiresIn: Retrieves the number of seconds the access token is valid for.
• getApprovedScopes: Retrieves the scopes approved by the user during authentication.

Tests:

• Updated the OAuthOneTest and OAuthTwoTest class to use the new getter methods.
• Added assertions to verify that the getter methods return the correct property values.

Benefits to End Users

These updates provide more convenient methods for retrieving user information, making it easier to work with user data. The changes are backward-compatible and do not break any existing features. Note that while the Two\User getters enhance data retrieval, the properties still require type-hinting for full static analysis compatibility.

I don't think we need all this for public properties?
