[bug] Health check for guac rest docker is broken

[mlieberman85]

Describe the bug
When running docker compose on guac-demo-compose.yaml it appears that GUAC REST component fails the health check. Here is the output of docker ps:

CONTAINER ID   IMAGE                         COMMAND                  CREATED      STATUS                    PORTS                    NAMES

Even though it fails the check though it seems to be healthy and working. Here's the output of the REST logs:

In addition docker compose ls says:

NAME                STATUS              CONFIG FILES
talks-guac          running(5)          /Users/mlieberman/Projects/talks-guac/guac-demo-compose.yaml

According to our docs: https://docs.guac.sh/setup/ -- The running(5) should be a running(7) I don't know if we changed stuff so that 5 is now accurate and the docs are incorrect or if the docker compose is broken.

To Reproduce
Run: docker compose up --force-recreate against the most recent release of guac-demo-compose.yaml.
