test(eks): Dockerfile used in an integ test fails (#27686)

I changed because `node:18-alpine3.13` image is no longer accessible and occurred errors.

------
failed to solve with frontend dockerfile.v0: failed to create LLB definition: docker.io/library/node:18-alpine3.13: not found
```

Also, I updated package-lock.json since there was a difference from package.json.
