w32: Confirm the 639-1 code for Venda is "ve"

https://www.loc.gov/standards/iso639-2/php/code_changes.php says that
ve is indeed the 2-character code for Venda:

This alpha-2 ISO 639-1 code was approved in 1999 and included in
ISO 639-1: 2002. It was mistakenly missing in earlier versions of
the tables on the ISO639-2 web site. As of January 2003, it has
been included.
