Creation of dynamic property Fastly\Configuration::$apiKeys is deprecated

[lucasfilippi]

With PHP 8.2 , dynamic properties are deprecated so your exact snippet is not working anymore :

$config = Fastly\Configuration::getDefaultConfiguration()->setApiToken('YOUR_API_TOKEN');

Resulting in my unit test

ErrorException: Creation of dynamic property Fastly\Configuration::$apiKeys is deprecated in /usr/src/app/vendor/fastly/fastly/lib/Configuration.php:193

You have to either use #[\AllowDynamicProperties] on your class or declare the property private array $apiKeys = [];
