Docker compose files don't read TRACETEST_DEV from env vars correctly

[danielbdias]

To run our demos on dev mode we've created an env var TRACETEST_DEV which is injected on docker.

However, in some cases, docker ignores this env var and only considers it if we set it explicitly on docker compose, in a command like:

TRACETEST_DEV=true docker compose up -d

We need to figure out if there is a simpler way of docker compose to consider this variable on docker compose up without needing to set up it explicitly.
