Documentation

https://docs.python.org/3/library/sys.html#sys.winver says:

The value is normally the first three characters of version.

That has not been true since Python 3.11. It should probably be updated to say something like, "The value is normally the major and minor versions of the running Python interpreter," or something along those lines.
