version metadata is incorrect

[andrewzah]

Hello, I'm packaging this library with Nix as a dependency for pulpcore, which specifies

"uuid6>=2023.5.2,<=2024.7.10"

but it can't resolve correctly due to hardcoding the version to 0.0.0.dev0 in setup.py:

if GITHUB_REF and GITHUB_REF.startswith(PREFIX):
    prefix_len = len(PREFIX)
    VERSION = GITHUB_REF[prefix_len:]
else:
    VERSION = "0.0.0.dev0"

---

the standard resolution is to update this in the commit that is tagged for that release.
