Switch to Nginx server in Dockerfile and add config

The Dockerfile has been updated to use Nginx server instead of the previously used dotnet/aspnet and the default listening port has been changed to 80. The new nginx.conf configuration file has been added and copied over to the right location in the Dockerfile setup. This change allows our application to use Nginx to better manage web traffic.
