feat(docker): Use jobs over workflow dependency

Workflow dependencies relies on a single workflow,
which make build pipelines for multiple docker containers
complex and most of the time erratic.

Move to single jobs dependency based with a internal action
to check and build images if needed improve the logic of the
process and allow to visually see the running pipeline.

The pipeline will run on following cases:
- On pull_request if .versions file is changed, but not
  publishing images on the registry.
- On push or workflow_dispatch, publishing to defined registry.
