[Data Ingestion and Storage] - Issue when buiding the Docker image in the CI/CD Pipeline

Hi Giorgos, we are facing an issue when building the Docker image inside the Pipeline (using de DnD Docker feature).

One of the errors we have seen in the log console was:

$ docker build -t $REGISTRY_IMAGE:$CI_COMMIT_SHA .
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

@jabefa sent you by email last week all the info:

Project: https://gitlab.eclipse.org/eclipse-research-labs/datamite-project/data-governance/data-governance-backend

CI Task with the error: https://gitlab.eclipse.org/eclipse-research-labs/datamite-project/data-governance/data-governance-backend/-/jobs/400964

I've also attached the task logs to this issue.

The docker and docker-dind version used was referencered from the examples in https://gitlab.eclipse.org/eclipse-research-labs/datamite-project/docs/-/blob/main/ci_cd.md?ref_type=heads. I've also tried with the latest version and produced the same error.
