chore(3p/sources): Bump channels & overlays r/6361

* //3p/sources: switch stable channel from 21.11 (!) to 23.05

* //users: adapt to emacsUnstable to emacs-unstable rename

* //users/grfn: use default Linux kernel version everywhere,
  as 5.15 has broken in this version of nixos-unstable.

* //3p/cgit: adapt to git 2.41.0

  The committed changes are the same as the [patch1] I've submitted
  to cgit-pink which is in turn based on Christian Hesse's [patch2].
