tor 0.4.6.x has disappeared from deb.tpo

That makes CI fail in sbws. It was there before (see https://gitlab.torproject.org/juga/sbws/-/jobs/17357#L6159) but now is not (see https://gitlab.torproject.org/juga/sbws/-/jobs/17996#L42). It's still listed in https://gitlab.torproject.org/tpo/core/team/-/wikis/NetworkTeam/CoreTorReleases and in dist.tpo.

Maybe it's not there cause it fails to build?, could removal of packages in deb.tpo be announced in tor-packages or some other ml?
