Pages job in .gitlab-ci.yml is untagged and clones whole repository (1)

In our CI workflow, there is a pages job that is only run when a production build is being done (which happens on a merge to master or when a tag is created). However, this job fails currently because it has no tags set. As a workaround, I enabled the TwoRem Docker Runner to run untagged jobs, but this is not something that I want to keep in the configuration.

Also, the GIT_STRATEGY variable is wrongly set to clone, which should be set to none. There is no need to clone the Quizzard Git repository for the pages job, as it only needs the artefact generated by the previous package job.

• Add some tags to the pages job in .gitlab-ci.yml.
• Change GIT_STRATEGY to none for the pages job in .gitlab-ci.yml
