PHP 8.4 deprecation : Implicitly nullable parameter types

[kevin-emo]

Hello,

Implicitly nullable parameter types have been deprecated since PHP 8.4 : https://wiki.php.net/rfc/deprecate-implicitly-nullable-types

This deprecation outputs a lot of logs such as :

deprecation.INFO: Deprecated: Fintecture\Client::__construct(): Implicitly marking parameter $httpClient as nullable is deprecated, the explicit nullable type must be used instead {"exception":"[object] (ErrorException(code: 0): Deprecated: Fintecture\\Client::__construct(): Implicitly marking parameter $httpClient as nullable is deprecated, the explicit nullable type must be used instead at /var/www/html/vendor/fintecture/fintecture-sdk-php/src/Client.php:60)"} []

As this repository supports "php": ">=7.2", fixing it should be safe 👍 !
