fix: use non-root nginx image for Kubernetes runAsNonRoot compatibility

Browse Source 
Switch from nginx:stable-alpine to nginxinc/nginx-unprivileged:stable-alpine.
The unprivileged image runs as nginx user (UID 101) on port 8080, satisfying
the runAsNonRoot: true security context in Kubernetes.

Fixes: https://github.com/cartsnitch/infra/issues/65
