nixpkgs/maintainers/scripts/update-luarocks-packages
Matthieu Coudron 6402fbb6b8 update-luarocks: can install for a different lua
the recent luarocks can install for a different interpreter than the one
running luarocks.
Due to the way the update is done on nix, it seems more practical to use
this feature than running the script with different luarocks-nix ?
