core: The property is not readable because it is typed "string"

API Platform version(s) affected: 2.6.0

Description
When doing a PATCH operation with a nested collection which has typed properties, it throws an exception

How to reproduce

/**
 * @ApiResource(denormalizationContext={"groups"={"group:write"}})
 */
class Group {
    /**
     * @ORM\OneToMany(targetEntity=Item::class, mappedBy="group", cascade={"persist", "remove"}, orphanRemoval=true)
     * @Groups({"group:write"})
     */
    private Collection $items;
...
}

/**
 * @ApiResource
 */
class Item {
    /**
     * @ORM\Column(type="string", length=255)
     * @Groups({"group:write"})
     */
    private ?string $name;
...
}

PATCH /api/groups/1
Content-type: application/merge-patch+json
{
"items": [{"id": "/api/items/1", "name": "test"}]
}

The property "App\Entity\Item::$name" is not readable because it is typed "string". You should initialize it or declare a default value instead.
