Does not detect alternative Cashier model

[dnnp2011]

My application uses a Team model instead of the default User model in Cashier, however, your RecordStripeEvent class determines the auth model via: $authModel = config('auth.providers.users.model') ?? config('auth.model');

Simply updating this to check for Cashier's CASHIER_MODEL env variable would fix this issue:

$authModel = config('cashier.model') ?? (config('auth.providers.users.model') ?? config('auth.model'));
