releng: move officialRelease to version.json

This was causing a few bits of suffering downstream, in particular, in
the NixOS module, which, after this change, can have the
`officialRelease` stuff in *it* completely deleted since we now have
correct defaulting in package.nix for it.

It also eliminates some automated editing of Nix files, which is
certainly always welcome to eliminate.
