chore: prevent normalization of semver versioning (#1292)

When there is a patch version added to semver versioning, setuptools.setup(version) will normalize the versioning from `-patch` to `.patch` which is not correct SEMVER versioning. The added feature with setuptools.sic(version) will prevent this from happening.
