x11-terms/kitty-*: drop "inactive" proxy-maint

Inactive in the sense that I've been the primary maintainer for a while
now and others haven't really needed to touch it even if they wanted to.

Just to avoid unnecessary CC on bugs, they are free to re-add themselves
if for some reason I cannot maintain this anymore.
