Symfony version(s) affected: 5.3.3

Description
Denormalizer breaks with an error Data expected to be an array, string given. when it handles an object, which contains a generic-like annotation, but is not an array or iterable.

How to reproduce

interface Foo {}

/** @template TFoo of Foo */
interface Bar {}

final class FooBar {
    /** @var Bar<Foo> */
    public Bar $bar; // This prop will fail
    // ...
}

Possible Solution
I digged it in PhpDocTypeHelper, which is part of phpDocumentor, so I don't know how to solve it. 😟
