PHP 8.5 Compatibility Error: Attribute applied to abstract class.

[LeoAdamek]

In PHP 8.5 and newer, it is no longer permitted to use an attribute on an abstract class. Currently this is being done in at least the following location:

GraphQLBundle/src/Annotation/Builder.php

Line 17 in d9c6f53

#[Attribute(Attribute::TARGET_PROPERTY | Attribute::TARGET_METHOD)]

This prevents the package from working on PHP 8.5 completely, which is a problem for platforms which only support the current PHP version.
