Social Signup should fetch the correct name field from the authentication

User’s name is not fetched from Google; it displays their email alias instead.

• Get basic profile: If signed in, you can retrieve the user's basic profile information using auth2.currentUser.get().getBasicProfile().

• Extract the name: The getBasicProfile() method returns an object containing various profile details, including getName(), getGivenName() (first name), and getFamilyName() (last name).
