We do the build of our artefacts inside a container image, and we need
to expose some env vars to the container so ORAS can be used there to
push the artefacts we want to cache to ghcr.io.
The env vars we're exposing are:
* ARTEFACT_REGISTRY: The registry where we're going to save the
artefacts.
* ARTEFACT_REGISTRY_USERNAME: The username to log in to the registry, as
ORAS does not use the same json file used by docker.
* ARTEFACT_REGISTRY_PASSWORD: The pasword to log in to the the registry,
as the ORAS does not use the same json file used by docker.
* TARGET_BRANCH: The target branch, which will be part of the tag of the
artefact, as we may end up caching the artefacts for both main and
stable branches.
