[BUG] cli panic on bad env_file properties

[mjpowersjr]

Description

Admittedly it took me way to long to spot this problem in a docker-compose.yaml file :-)

The following will cause the docker compose cli to panic, and the error message does not give the user a hint as to what's wrong:

env_file:
  - file: .env
    required: true

changing the same snippet to the correct definition fixes the panic:

env_file:
  - path: .env
    required: true
