1 additional nginx ENV to support deployment in Kubernetes

Since Adobe cloud is not flexible we are making warden.dev environments available to QA by deploying them into AKS. There is one setting that is missing from the nginx container that would make my life simpler and not introduce any more complexity since it can be defaulted to its current value.

I propose the following change. Just add a new ENV for NGINX_RESOLVER

This change allows me to use the same images for my dynamic branch environments in AKS as our devs use locally, cutting down on maintenance. Does anyone else have a need like this or have another suggestion for me?
