Per @dchan.
- Create GitLab repo: https://gitlab.wikimedia.org/repos/mediawiki/services/zotero
- Set up .gitlab-ci.yml file to create images
- Migrate production over to new docker image name (repos/mediawiki/services/zotero)
- Get everyone to migrate local development versions, and change docs
- Archive gerrit repo: https://gerrit.wikimedia.org/g/mediawiki/services/zotero (need to create a task for this, it's moderately involved)
