[Php83] Remove get traits class as ancestors collection on AddOverrideAttributeToOverriddenMethodsRector

[samsonasik]

continue of PR:

• [Php83] Allow indirect override abstract method on Grand Child on AddOverrideAttributeToOverriddenMethodsRector #6512

since we skip override only trait anyway, we can just remove it from ancestors collection, so only parent classes.

-$parentClassReflections = array_merge($classReflection->getParents(), $classReflection->getTraits());
+$parentClassReflections = $classReflection->getParents();

as add #[\Override] on non-empty trait is not-allowed, which must rely on parent class method which not empty first to allow add it.

All checks have passed 🎉 @TomasVotruba I am merging it ;)
