Adapt ContactsPermission to iOS 18, changing the limited status to return as authorized.

After iOS 18, a new status limited was added to CNAuthorizationStatus - ‘This application is authorized to access some contact data.’ In the limited status, I tried using CNContactStore to fetch contact data, and it successfully retrieved the corresponding data selected by the user. Therefore, I believe this status should be treated as authorized.
