[🌟 Feature Request] Support UUID v7

[XChikuX]

UUID v7 is becoming extremely popular due to it's timzone and lexicographical sorting features.

Let's make it a standard for redis-om as well.

Since it creates new UUID types, I doubt there will be any backward compatibility issues or collisions

Update:

• On further investigation it seems as though ulid is compatible with UUID at 128 bits
• I think this request would just translate to updating to python-ulid 3.0.0 in that case

I don't see a reason to stick to v1

Seems reasonable to me!
