Describe the bug

Dockerfiles for the examples want to copy files into the container that are no longer (package-lock.json) under version control since #614.

Reproducing the bug

Run a container from any of the examples' Dockerfiles or any of the compose instructions in the frontend/examples README file, e.g.:

docker compose -f deploy/docker-compose/base.yaml -f deploy/docker-compose/todo-react.yaml -p "hanko-todo-react" up --build
