Find the {@link Version} for the short ordinal value.

If the short ordinal represents a known version ({@link KnownVersion}) then return
that instead of constructing a new {@link UnknownVersion}.

@return a known version ({@link KnownVersion}) if possible, otherwise an
        {@link UnknownVersion}.
