Latest release should be v2.2.1 not v0.2.1

[jmrohwer]

HEAD on main is currently tagged v0.2.1 and this is the version listed as the current release. However, the previous release was v2.2.0, so it appears that this should be v2.2.1. The current state will mess up versioning.

@jmrohwer thanks for the heads up! The GitHub Release got the version wrong and has been updated accordingly. The release on PyPI is correct though. See the pyproject.toml:

[project]
name = "pyenzyme"
version = "2.2.1"
