Solo Call-Flake

A GH Actions extracts call-flake.nix from NixOS/nix on Sundays onto a flake.nix wrapper …

Special thanks to @nrdxp for the idea and prototype and @figsoda for the trick to make it work perfectly with subflakes / superflakes → (call-flake ../.).inputs. *

* If you have worked with subflakes accessing the superflake, this avoids the unstable state between the two locking files of super- & subflake (when used with inputs.super.url = "path:../.";) in which they flip-flop regularily.
