Luke Granger-Brown b35e358eb5 refactor(ops/nixos): migrate to depot module arg
Previously the depot argument was provided as config.depot, but the "new
way" of doing things (which is more like the args list provided in the
rest of the depot) is to provide this as the "depot" NixOS module
argument instead.
