For #974

Overall looks good. Since I am usually spending my out of work time to read/comment/review stuff in github or with documentation, I will merge this potentially early next week when @kba approves as well.

Does anyone know why there is no CI for the last commit here? Has our plan run out of capacity for this month incidentally?

Fixed, there was a colon missing when you added the docker_layer_caching: true option to setup_remote_docker, it's runing now https://app.circleci.com/pipelines/github/OCR-D/core/1760/workflows/e57a7630-045f-4641-bca4-8e30f0ecc78e

But we are out of credits:

However, so far everything still seems to work. CI provider has been very generous so far, we've been over the quota basically every month for a long time, so I hope the generosity continues 🤞
