Add void as return type (deprecation php8.4)

Deprecation message:

Method
"Symfony\Component\DependencyInjection\Extension\ExtensionInterface::load()" might add "void" as a native return type declaration in the future. Do the same in implementation "SergiX44\NutgramBundle\DependencyInjection\NutgramExtension" now to avoid errors or add an explicit @return annotation to suppress this message.
