Adjust .gitlab-ci.yml to use correct registry when forking
Context
CI Build
Summary
The predefined variables section contains a hardcoded repository location which is not possible to push to in forked projects.
Steps to reproduce
Fork this project, make a commit and see the preparation step failing :(
What is the current issue behavior?
Pushing to the base projects registry fails, See !22 (merged)
What is the expected correct behavior?
A push to the forked projects repository should succeed.

Possible fixes
We should probably use CI_REGISTRY_IMAGE instead of the hardcoded string.
