This PR changes /infra/app/services/main.tf to use a different configuration that exercises the functionality added in 474. Specifically, it uses a separate docker image (https://hub.docker.com/r/rocketnovadockerhub/tiny-env-test) which should (if everything is set up correctly) show something like this:

Hello, World!

Custom env var: 100

Custom secret: 200

Testing steps:

1. Deploy these changes. I used make infra-update-app-service APP_NAME=app ENVIRONMENT=dev
2. Navigate to the ECS task's LB url. It should display something like the above (showing whatever value you set the Parameter Store secret to)
