📚 Description

Since PostgreSQL v18 adds native support to work with UUID v7 and considering that Validator already supports RFC9562 UUIDs, this pull request expands the versions type including the 6, 7, and 8 in the uuidRule. Also adds corresponding unit tests to ensure proper validation of these new UUID versions.

Validation rule updates:

• Updated the uuidRule in src/schema/string/rules.ts to accept UUID versions 6, 7, and 8, in addition to the previously supported versions.

Testing improvements:

• Added new unit tests in tests/unit/rules/string.spec.ts to verify validation for UUID versions 6, 7, and 8, as well as combinations of supported versions.
