[Sciencebeam/Libero editor migration] create example pipeline
Description; an agreement was made with Cloud68 in support of migration of the Scoienecbeam and Libero editor repos to GitLab that we use the existing Jenkins infrastructure. Cloud68 will help with this, but we need to set up an example for guidance purposes;
- secrets set up for PyPI, TestPyPI and Dockerhub (Yannis to assist here)
- Daniel (eLife) with support from @BenWh to setup example GitLab pipeline, the result is that we don't need to adopt the Jenkins solution.
