Switch to alejandra for nix formatting

I mostly wanted a formatter that would format `inherit` blocks
vertically, because otherwise they are super hard to read when diffing
or even just editing.  Both alejandra and the new nixos/nixfmt format
verically like this, but alejandra has slightly better format (I guess)
and for some reason nixfmt did not respect my `GLOBIGNORE` setting when
doing `nixfmt **/*.nix` so it was trying to format stuff in `_/nix`, and
failed. So anyway I went with alejandra.
