The current full example task fails as /bin/sh -c only accepts a single argument.

The current example

override-container-command: |  /bin/sh  -c  php artisan migrate --force --ansi && \  php artisan db:seed --force --ansi && \  php artisan config:clear --ansi

will produce an ecs run-task equivalent of:

 aws ecs run-task ... \ --overrides '{ "containerOverrides": [ { "name": "foo", "command": ["/bin/sh", "-c", "php artisan migrate --force --ansi && \\", "php artisan db:seed --force --ansi && \\", "php artisan config:clear --ansi"] } ] }'

which executes the first argument (artisan migrate), but produces line 0 errors on the other commands.

It would be great to support a shell command helper that merges the [multiline] commands into a single argument (when they trail with a \?). For now, I think we must do everything on a single line, e.g.

override-container-command: |  /bin/sh  -c  php artisan migrate --force --ansi && php artisan db:seed --force --ansi && php artisan config:clear --ansi

and should update the example?
