Update 130-docker.mdx (#7004)

If we run `npm ci` after `COPY . .`, packages will need to be reinstalled upon every build since `COPY . .` directive invalidates the cache if any source file changes. Having `RUN npm ci` before `COPY . .` ensures that npm packages don't get reinstalled if `packages.json` doesn't change.
