feat(simplify): Use jobs instead of workflow dependencies

Workflow dependencies relies on a single dependency, which make build
pipeline 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 was touches, but not publishing
  images on the registry.
- On push or workflow_dispatch, publishing to ghcr.io registry.
