Problem

This is for later on but making a script for Proxmox and adding it to helper-scripts would be useful

Proposed solution

Using helper-scripts template https://github.com/community-scripts/ProxmoxVE/blob/main/docs/contribution/README.md for making a Proxmox installer script for fluxer self-host

Notes (optional)
