Description

    {
        return [
            self::PROPERTY_NAME => [
                'property' => self::PROPERTY_NAME ,
                'type' => Type::BUILTIN_TYPE_ARRAY,
                'required' => false,
                'openapi' => [
                    'name' => self::PROPERTY_NAME,
                    'schema' => [
                        'type' => 'array',
                        'item' => [
                            'type' => 'string'
                        ]
                    ],
                ],
            ],
        ];
    }

In the above code anything in the 'openapi' is not shown in the openapi docs.

    {
        return [
            self::PROPERTY_NAME => [
                'property' => self::PROPERTY_NAME,
                'type' => Type::BUILTIN_TYPE_ARRAY,
                'required' => false,
                'schema' => [
                    'type' => 'array',
                    'items' => [
                        'type' => 'string'
                    ]
                ],
            ],
        ];
    }

But placing the properties outside of 'openapi' does change the openapi docs. This is against what the ApiPlatfrom docs says on this page: https://api-platform.com/docs/core/filters/.

How to reproduce

1. Create a custom filter implementing interface ApiPlatform\Doctrine\Orm\Filter\FilterInterface
2. Implement the getDescription method like the two examples above
3. See the first example doesn't work, but the second does
