nix profile stores a 'resolved' source attribute #10077
Description
Describe the bug
Currently whenever an package is installed using nix profile, the fragment of an installable is 'resolved'. For instance, nixpkgs#nodejs is implicitly resolved to flake:nixpkgs#legacyPackages.x86_64-linux.nodejs. This is somewhat confusing.
It would be nice if the original source flake uri is stored.
In addition, this could be a steppingstone toward supporting #10064.
Steps To Reproduce
$ nix profile install nixpkgs#nodejs
$ nix profile list
...
Name: nodejs
Flake attribute: legacyPackages.x86_64-linux.nodejs
Original flake URL: flake:nixpkgs
Locked flake URL: github:NixOS/nixpkgs/9a9dae8f6319600fa9aebde37f340975cab4b8c0
Store paths: /nix/store/vz13mi0w75q96sfjxz2ylnv8812hvf34-nodejs-20.11.1
Expected behavior
It would be nice to just see the original flake URI instead:
$ nix profile install nixpkgs#nodejs
$ nix profile list
...
Name: nodejs
Installable: nixpkgs#nodejs
Locked installable: github:NixOS/nixpkgs/9a9dae8f6319600fa9aebde37f340975cab4b8c0#legacyPackages.x86_64-linux.nodejs
Store paths: /nix/store/vz13mi0w75q96sfjxz2ylnv8812hvf34-nodejs-20.11.1
