This PR updates all example Dockerfiles that were using `node:18-alpine` to `node:20-alpine` to align with current LTS and address known issues in Node 18 images. - examples/with-docker/Dockerfile - examples/with-docker-compose/next-app/prod.Dockerfile - examples/with-docker-compose/next-app/dev.Dockerfile - examples/with-docker-multi-env/docker/development/Dockerfile - examples/with-docker-multi-env/docker/production/Dockerfile - examples/with-docker-multi-env/docker/staging/Dockerfile I verified local builds for each example. No behavior changes; docs/examples only. https://github.com/vercel/next.js/issues/78465 --------- Co-authored-by: Joseph <joseph.chamochumbi@vercel.com>
