Changes proposed in this pull request:

If you previously relied on another bound object (such as a service provider instance) as $this inside these callbacks, you should move those values into closure captures using use (...).

Pull request overview

Updates the Socialite provider extension callback to remain compatible with Laravel 13’s Support\Manager behavior change around callback $this binding.

Changes:

• Capture the current SocialiteWasCalled instance into a local variable before registering the SocialiteManager::extend callback.
• Use the captured instance inside the callback instead of relying on $this being bound as expected at invocation time.
