The operations option of parameter attributes on properties only accepts operation instances: passing a class name throws a raw TypeError: Cannot use "::class" on string. Since the restriction matches on the operation class anyway, accept class names too (they can be mixed with instances).

Before

#[ApiResource(operations: [new GetCollection(), new Get()])]
class Book
{
    #[QueryParameter(key: 'search', operations: [GetCollection::class])]
    public string $name = '';
}

TypeError: Cannot use "::class" on string

After

search is only declared on GetCollection. A class name that is not declared on the resource throws the same exception as an instance:

Parameter attribute on property "name" is restricted to the operation "ApiPlatform\Metadata\Patch" which is not declared on the resource "App\Entity\Book".
