[ Feature Request ] : Add Nix Package Manager Support to Maestro WAAS

[byteshiva]

Description:

Please consider adding support for the Nix package manager to Maestro Workflow. Nix offers reliable and reproducible package management, and its inclusion would expand Maestro's compatibility and utility.

Implementation ideas:

1. Introduce a "Nix" step type.
2. Offer Nix as a default package manager option.
3. Update documentation to include Nix usage.

Thank you for considering this feature request.
