examples: Have cron container depend on the app container

The cron container requires the files created by the app container, to
start its cron tasks. There is a potential race condition here, where
cron starts to run before the app container is even up, before the app
container has populated `/var/www/html`. This is undesired and easily
solved by making sure cron depends on the app container.
