Symfony version(s) affected

5.4.2

Description

Given a User entity (for demonstration purposes, not related to security) annotated with

 * @ORM\Id()
 * @ORM\GeneratedValue(strategy="CUSTOM")
 * @ORM\CustomIdGenerator(class=UuidGenerator::class)
 * @ORM\Column(type="uuid")
 */
private Uuid $id;

And the framework.yml configured with

uid:
    default_uuid_version: 4

Then doctrine will unexpectedly enter a UuidV6 UUID.

INSERT INTO users (id, email) VALUES (?, ?) 1={"Symfony\\Component\\Uid\\UuidV6":"1ec6f2d7-4149-60de-ac5b-174b92ac32c9"} 2="6fbb2834-21c2-4145-9d24-cc [...]"

The article https://symfony.com/blog/new-in-symfony-5-3-uid-improvements suggests that once configured, this should be UuidV4.

I think the documentation https://symfony.com/doc/current/components/uid.html also needs updating. as it says "There is no generator to assign UUIDs automatically as the value of your entity primary keys, but you can use the following" which is unexpected, considering there is the UuidGenerator::class, even though it seems to only generate V6 UUIDs.

Thank you.
