Feature request: Use nginx-unprivileged to allow to run as non root user

[rasmusson]

Im trying run cyberchef in kubernetes and trying to run it as a non root user as general security best practise. Because nginx is running as root I can't do that.

Describe the solution you'd like
I¨m hoping you can start using nginxinc/nginx-unprivileged in your docker container instead of the regular one running as root.
