Fix CI for Docker-in-Docker changes

Recently, changes were made in the configuration of the CI runners at ASTRON. This broke our pipeline. This has been fixed by replacing all references to services: docker with tags: dind.

Note that, as a result of these changes, image caching no longer works. This needs to be fixed by adding a docker pull to retrieve the cached image. This will be done in another MR.
