Description

Currently, we have our flake-inputs Github Action for updating the flake packages. We have discovered that the current solution is not great as each package may have different needs or update mechanisms while the current action only uses nix-update.

A better mechanism should be the introduction of passthru.updateScript and customizing, where necessary, how the package might want to update itself. This is the approach that nixpkgs currently uses, and ideally, we should explore a similar solution (if not using the same tooling).

So far, we should explore:

• How we can integrate from nixpkgs both maintainers/{update.nix,update.py} scripts into this flake.
• If not possible, adapt it to meet our needs.
• Update our repository Github Actions to run effectively the update mechanism.
