Need to specify use of internal docker image hub (Artifactory) vs external docker hub

[hlgr360]

We need to document the process to get an account to the internal docker repo at Artifactory (plus internal Go.CD pipeline) vs the external Haufe docker hub account and the external Go.CD pipeline

Here is the snippet from an email explaining the process (from @DonMartin76):

Build on commit and push image into docker.hub for the OSS one? Does it end there + a demo compose file?
Yup, that’s how it works. If you check in and push to github, it automatically builds and pushes to docker hub, given the tests still work, obviously. If no changes are detected, it builds once a week.

Maybe we also need in here or in a seperate document to describe both the jenkins and the go.cd CI/CD pipelines for building and deploying docker images (incl. Examples)
