feat: Allow UUIDv6/7/8 in UUIDField validation (#221)

Why
---
Currently the UUIDField type supports only UUIDv1-5 and to use a newer UUID version we need to use StringField.

How
---
Manually implemented UUID validation, adding support for versions 6, 7, and 8. Also added support for the "max" UUID, which is now part of the spec.

Test Plan
---
Added a UUIDv7 value (from https://uuid7.com/) to test cases.
