chapter 02: resource limits for grocery-store and inventory too stringent

[fabricev]

Both containers start and stop.

Had to raise the memory limit (set at 50M) to 80M to have them running. Below is a docker stats view to show the actual usage is above the limits set in the docker-compose.yml

Thanks for reporting this! I've updated the memory requirement as per your suggestion ba776b7
