Fix docker compose configuration with the new tracker container image

[josecelano]

The Torrust Tracker container image has changed.

We have to upgrade the configuration to use the latest version.

Integration tests fail for pull requests because the tracker container cannot start.

The significant changes introduced were:

• Rename some env vars: TORRUST_TRACKER_API_TOKEN->TORRUST_TRACKER_API_ADMIN_TOKEN
• Database folder was moved to a new location

You can see here on example of workflow failing:

You can see in the docker ps output that the tracker service is not running:
