[Bug]: Switching from application/x-www-form-urlencoded to application/json when request body has an integer property shows wrong object

Description

Demo

Attached with this issue there is a screen recording of the issue; it's a little hard to explain in words but very easy to understand when observed.

Steps to reproduce:

1. Make a DTO with an integer property (OA\Property (#[OA\Property(type: 'integer')])
2. Make a POST/PUT route with a RequestBody where the content contains (at least) two MediaType objects: one should be of type application/x-www-form-urlencoded and the other application/json. Both should use the DTO defined in 1.
3. Go to /api/doc and find the call you defined.
4. Click on "Try out" making sure that application/x-www-form-urlencoded is selected in the dropdown
5. Switch the dropdown to 'application/json`

Expected result:

• The content is changed to a JSON with the integer field containing 0. For example: { "myIntegerVar": 0 }.

Result:

• The content is changed to a JSON where each key is an object of the form { "myIntegerVar": { "value": "0", "errors": [] } }.

Code example

With a fresh symfony and nelmio/api-doc-bundle installation, the following code shows the error.
If anyone would find it useful, I can provide the full project.

Controller

<?php
// src/Controller/DummyController.php

namespace App\Controller;

use App\Model\DummyRequestModel;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Nelmio\ApiDocBundle\Attribute\Model;
use OpenApi\Attributes as OA;
use OpenApi\Attributes\RequestBody;
use OpenApi\Attributes\Schema;
use Symfony\Component\Routing\Annotation\Route;

class DummyController extends AbstractController
{
    #[Route('/api/dummy', methods: ['POST'])]
    #[RequestBody(content: [
        new OA\MediaType(
            mediaType: 'application/x-www-form-urlencoded',
            schema: new Schema(ref: new Model(type: DummyRequestModel::class))
        ),
        new OA\MediaType(
            mediaType: 'application/json',
            schema: new Schema(ref: new Model(type: DummyRequestModel::class))
        ),
    ])]
    public function dummyAction()
    {
        return $this->json(new DummyRequestModel());
    }
}

DTO

<?php
// src/Model/DummyRequestModel.php

namespace App\Model;

use OpenApi\Attributes as OA;

class DummyRequestModel
{
    #[OA\Property(type: 'integer')]
    public int $foo;
}

Thanks in advance for all the thoughts and help :)
