Add Jazzy debians when they are ready

[JesusSilvaUtrera]

Desired behavior

Right now, the code from Andino main repo is being added and compiled by source on the jazzy branch, but in the future it would be nice to add it using debians, just like it's done in the humble branch, because it's cleaner and safer (it would only use the release versions). For that, we need to do a release of the Jazzy packages on the main repo first.

Implementation suggestion

Add the debians to the docker/requirements.txt file and remove the source code installation from the Dockerfile.

Additional context

No rush is required for this issue, I am opening it just so we don't forget to do it in the future.
