Follow-up: Improvements for PR #476 (Added Nix development flake)

[HopHouse]

Important

Please consider merging into t3rp/feature/nix-dev-flake or let me know if maintainers prefer a direct push.

Context

This PR contains improvements for @t3rp's PR #476.

Initially, I encountered some issues in using the correct Python version which is both:

• Available on my OS
• Compatible with venv requirements

I did not have Docker/Podman installed on my machine, so I created a Nix flake for my Proxmox environment.
Upon seeing @t3rp's Pull Request, I decided to continue its work and merge it with mine.

Solution

Merge @t3rp flake and mine to:

• Add Proxmox support
• Pin the Python version
• Make it available on all systems through flake-utils.lib.eachDefaultSystem
• Define devShells and Apps separately
• Add the flake.lock to make it fully reproducible
• Keep as much as possible the code from @t3rp

Testing

All the derivation works well on my machine.
