Fix the prerender cache update error with the example Dockerfile (#54870)

Browse source 
It seems the app router attempts to write its cache to both `.next/cache` and `.next/server` in docker.

This fix should fix standalone output server's error `Failed to update prerender cache... [Error: EACCES: permission denied...` when deployed in a docker container with the example Dockerfile.
