docs/82619: bsd-family-tree update request

[SODA Noriyuki]

NetBSD minor releases were called "patch release" until NetBSD-1.6.X,
but minor releases are now called "maintenance (stable) release" (for
[2-].X) or "security/critical release" (for [2-].X.Y) as described in
the following page:
http://www.netbsd.org/Releases/release-map.html

So, I made one more change, please apply the following change as well.
Thanks.
