Update stripe data

[nudecode]

Had to update the registration controller to pay for the product using the product id that is automatically set by stripe, could not find anywhere to set the id to the starter id.

code change below;

$newSubscription = $user->newSubscription('subscribed', 'price_1KrCzQDiP27lLGBcYJcUqEBP')->create($request->payment_method, ['email' => $user->email]);

might want to look at updating the readme to reflect the changes in stripe?

Thanks for the content though, really enjoying it.
