[BUG][v3.1.0] Impossible to change RequestBody for openapi

[DeLm0re]

API Platform version(s) affected: 3.1.0

Description
With this new version, it seems impossible to change the request body description or content.

How to reproduce

Define an ApiResource with a Post operation like this

new Metadata\Post(
    routeName: 'api_multiple',
    openapi: new Model\Operation(
        requestBody: new Model\RequestBody(
            content: new \ArrayObject([
                'application/json' => [
                    'schema' => [
                        'type' => 'object',
                        'properties' => [
                            'ids' => [
                                'type' => 'array',
                                'items' => ['type' => 'string'],
                                'example' => ['1e677e04-d461-4389-bedc-6d1b665cc9d6', '01111b43-f53a-4d50-8639-148850e5da19'],
                            ],
                        ],
                    ],
                ],
            ]),
        ),
    ),
),

But on my swagger documentation, the request body is unchanged and it is the default one still

Additional Context
I'm using Symfony 6.2.5, everything work as expected so far
