[$] Removing Guix from Debian

As a rule, if a package is shipped with a Debian release, users cancount on it being available, and updated, for the entirelife of the release. If package foo is included in the stablerelease-currently Debian13("trixie")-a user canreasonably expect that it will continue to be available with securitybackports as long as that release is supported, though it may not beincluded in Debian14 ("forky"). However, it is likely that theGuix package manager will soonbe removed from the repositories for Debian13 andDebian12 ("bookworm", also called oldstable).
