With the following ApiResource:

#[ApiResource(
    operations: [
        new GetCollection(provider: EntityStateProvider::class),
        new Get(provider: EntityStateProvider::class),
        new Post(processor: EntityStateProcessor::class)
    ],
)]
class Entity
{
    #[ApiProperty(identifier: true)]
    public ?int $id = null;

    #[Assert\Ip(version: 'all')]
    public string $ip = '';

    public function __construct(?int $id = null, string $ip = '')
    {
        $this->id = $id;
        $this->ip = $ip;
    }
}

This patch turns the "ip" property's schema from

format: ipv6

SwaggerUI

into

oneOf:
  - format: ipv4
  - format: ipv6`

SwaggerUI

To better document that both ip versions are possible as input/output.

I saw there is a dedicated PropertySchemaOneOfRestriction class, but imo this IP format does not fit in there so I opted to keep it in the PropertySchemaFormat class. Extra PropertySchemaOneOfRestriction test was added to assert combining the two.
