Feature: create demo installer to setup workspace automatically

[achille-martin]

Currently, the "Getting Started" section details every step to setup the workspace for the demo app, but it might take too long for people to experiment with the demo.

The idea is to speed up the on-boarding process with a script that would setup the whole workspace automatically.

The script could include setup of:

• Virtual Machine Linux & Ubuntu 22
• Setup of python and pip3
• Download of main repo
• Setup of external dependencies
• Run of Linux demo app
• Build of Android app
• Run of Android app

According to comments from users:

• The feature of setting things up simply would be very appreciated (especially as a "quick start" option)
• It is easy to miss the python virtual env (which needs to be sourced at each session)

Implementation translation:

• Add a "quick start" option where the user can set the whole machine at the click of a button (rather than go through a long README)
• For the automation, start by breaking down the steps and then address each entity depending on the host (if relevant)
• Create sessions on the machine to use PyQt-CroM straight away (no python venv invocation for instance)

New idea from me (as an alternative setup for advanced users?):

• Create a docker image on Ubuntu that contains all required dependencies and then users can start and stop a container easily with no installation step almost. They can then add new dependencies to the docker and save it (needs to be added to the SOP)
• Extend the docker image to be run on Windows (for practicality of more beginner users): https://ubuntu.com/tutorials/windows-ubuntu-hyperv-containers#1-overview

As an even simpler alternative for beginner users:

• Create a script for VirtualBox that would setup the virtual machine with one click (including all basic Ubuntu dependencies) -> starting from Windows, or skip the step if already in Ubuntu (but might need a VM still to get the exact environment)
• Create a bash script that would install all the required dependencies where they are expected to be
  This would ensure the same consistent setup for everyone. People can then tweak the script to adjust to their needs.

There is a need to identify installation and running requirements depending on users:

User v / Phase >	Installation	Running	Experiments
Beginner	Simple, guided, from Windows	Simple, guided, prepared examples	NA
Intermediate	Simple, from Win or Ubuntu	Simple, running custom examples	Limited
Advanced	Any method, efficient	Any example and custom script	Versatile tool
