sdk: docker: use Apertis container to test

This test anonymously downloads and runs the hello-world image from Docker Hub which has a download rate limit of 100 pulls per 6 hours per IP address, see https://docs.docker.com/docker-hub/download-rate-limit/.

Depending on the docker image download usage during the previous 6 hours, this test may failed.

This limit doesn't exist in the gitlab registry, so replace hello-world by Apertis testcases-builder image to generate the PASSED message.
