Update Dockerfile for Next.js 16 and Node 20 compatibility

Switches base image to node:20-alpine for both build and production stages to ensure compatibility with Next.js 16 and Turbopack. Installs git earlier, improves commit hash retrieval with a fallback, increases memory for builds, and updates comments for clarity. GIT_COMMIT_SHA is now read from a file at runtime instead of being set as an environment variable.
