Current instructions to build dev environement are nearly all wrong on Debian 12

[CharlesNepote]

Current install instructions don't work on Debian 12.

Here is the way I managed to have a working dev environment:

# start with a fresh Debian 12 install, logged as root
apt install git sudo postgresql python3-venv -y
adduser folksonomy
usermod -aG sudo folksonomy
su folksonomy
cd ~
git clone https://github.com/openfoodfacts/folksonomy_api.git
cd folksonomy_api
python3 -m venv folksonomy
. ./folksonomy/bin/activate
pip install -r requirements.txt
sudo -i -u postgres createuser $USER
sudo -i -u postgres createdb folksonomy -O $USER
yoyo apply --database postgresql:///folksonomy
cp local_settings_example.py local_settings.py
uvicorn folksonomy.api:app --reload --host <my_ip_address_or_domain_name>
# => works
