[Enhancement] install.sh script for easy installation of a floresta node

[qlrd]

Describe the enhancement

Floresta is an amazing project but can be hard for non-experiencied users to properly install and configure the system. Many projects, such as rustup, brew or poetry, use a bash script that allows for an easier installation and configuration of the system.

This issue proposes exactly that, an install.sh script that installs dependencies, florestad/floresta_cli and configures a systemd service in a semi-customizable way, at least for debian (until now).

Use case

Imagine that the project has a domain, let's say https://vinteumorg/floresta and it is possible to install a floresta node through a command like https://vinteumorg/floresta/install.sh and in +- 5 minutes it is already possible to use it.

Additional context
There are already some scripts for Archlinux.
