zeroconf: fix an invalid argument error on Windows The idea that pyoxidizer was triggering the problem when standing up the previous incarnation of CI for Windows was misleading- it was a Windows problem in general. See the inline bug link. Unfortunately, there's no commit referenced there, and it looks like OP closed the report himself with the suggested workaround. IOW, very modern python may not work, but it's extremely unlikely that there are any users of this extension, especially on Windows.
