   Log Message:
   Correct the names for the NetBSD versions to use.

   This uses the faster "install.sh" script, and also omits the
   "rust-doc" subset, for a much faster installation.

   This is a temporary hack for this version, will be removed on
   the next go-around.

   Apologies for this going un-committed, only myself to blame.
   Should fix part of PR#56304.
