feat(docker-compose): run jackson service

[MissaDavid]

What does this PR do?

This PR intends to facilitate the deployment of the Jackson service, using docker compose. I transferred the docker command provided in the documentation into a generic docker compose file. I'm not sure what makes the most sense regarding the DB settings, so for now I have only added the Postgres env variables.

Fixes #61 (issue)

Type of change

• [X] New feature (non-breaking change which adds functionality)
• [X] This change requires a documentation update

How should this be tested?

1. Start your postgres DB
2. In your root folder, run:

docker compose up

This should create a container named jackson, running on port 5225. 3. The service is accessible at the following address: http://localhost:5225/. And if you go to http://localhost:5225/api/health, it will return your current version of Jackson (for me it was {version: "1.13.0"}).
