Getting userena deployed on Render

I replaced the URL() with re_path() and I modified the settings to be compatible with the current Django. I created the build script and I changed a little bit the project structure by moving the userena app to the demo folder. Now, the project is live on:

https://django-userna-ce.onrender.com/

The project contains old Django code, I suggest updating the entire project later to fit the current version of Django.
