folders not found inside /etc/nginx in RHEL9

[rfinotti]

Is your feature request related to a problem? Please describe.
During Nginx installation in RHEL OS, nginx will not create the SITES-AVAILABLE and SITES-ENABLED folders inside ../etc/nginx/, hence the NGINX-UI will fail when a new site is created as it will not find those folders.

Describe the solution you'd like
I would suggest adding the following piece of code to the install.sh

nginx_dir="/etc/nginx"
directories=("sites-available" "sites-enabled")

for dir_name in "${directories[@]}"; do
    directory="$nginx_dir/$dir_name"
    if [ ! -d "$directory" ]; then
        echo "Creating $dir_name directory..."
        mkdir -p "$directory"
    fi
done
