Fix: parameter change from version: str to vinfo: VersionInfo

Browse source 
Using `version: str` meant that version.parse_version_info implicitly
used the "{pycalver}" pattern. The changed parameter vinfo: VersionInfo
now requires the caller (with access to cfg.version_pattern) to provide
the correctly parsed vinfo.
