CloudTasksQueue::$config must not be defined

[ericksonlargura]

Laravel v12.34.0 added accessors to $config. Here is the exception thrown after the update:

exception: {
class: "Symfony\Component\ErrorHandler\Error\FatalError"
code: 0
file: "/app/vendor/stackkit/laravel-google-cloud-tasks-queue/src/CloudTasksQueue.php:38"
message: "Type of Stackkit\LaravelGoogleCloudTasksQueue\CloudTasksQueue::$config must not be defined (as in class Illuminate\Queue\Queue)"
}

v12.33.0 works just fine. Sorry for not providing a PR, if I manage to spare some time, I'll try to do that.

Thanks for the heads up, I have released with v5.0.2 with a fix!
