This commit addresses the issue of unstable key ordering in default.nix. Previously, the keys could appear in different orders such as "stable, beta, dev" or "beta, stable, dev". To simplify the reviewing process and minimize merge conflicts, this commit introduces the use of OrderedDict, ensuring consistent key ordering for upstream sources. Also, the gzip import was unused, so just drop it.
