Add non-interactive installation parameter

[C0wnuts]

Add a non-interactive installation method via a new parameter to be passed to the install.sh script.
Essential for automated/industrialized systems (e.g. via Ansible or another automated environment creation system).

Have you tested this thoroughly?

[C0wnuts]

Hi, I tested on Debian 12, Ubuntu 22.04 and WSL 2 (Windows 10 with ubuntu distro). It worked fine.
I tested on existed install (with some dependencies already installed like Docker or Curl) and on fresh install without any dependencies, just run the install script in non-interractive mod : ./install.sh -n

For the super admin setup via Django, I followed the official documentation here: https://docs.djangoproject.com/en/4.2/ref/django-admin/#createsuperuser

Awesome, can you add some documentation to the installation part of the README? After that I'll merge it into my fork.

I added some information inside the installation part. I hope that's enough, if not tell me what I need to add or change.

Looks good, but just a few nitpicks, see comments.

We need to re-open this one for 2.1.0.
