x11-wm/ctwm: update to 4.0.2

[fernape]

Summary

Sent by maintainer via PR 230901

Change PORTVERSION to DISTVERSION from the original submitted patch.

I'm not using implicit approval due to the (small) change in pkg-descr :-)

Test Plan

• portlint -AC OK
• poudriere builds for {10.4,11.1}{amd64,i386}, 11.2amd64, 12i386 OK

^^ I would say, we trust you enough to add that 's' to http implicitely (also other changes to pkg-descr :))

I was 99% sure that was the case, but better safe than sorry XD

Thanks!
