file_creator Docker workflow and dockerfile

[Mik-TF]

This PR proposes the Dockerfile and workflow (file_creator_publish.yml) for the file_creator written in V.

@brandonpille Can you have a look?

The Dockerfile should be OK.

EDIT: I set the PR as a draft until it works properly.

Thanks!

What works locally

For reference, the following commands give the desired result on a local computer.

• docker build --no-cache -t file_creator_image:1.0 .
• docker run --name file_creator_container -v .:/farmerbot -ti file_creator_image:1.0

So this is technically what we are aiming with the file_creator_publish.yml and docker-compose.yaml files, if I understand correctly.
