Do not run gitlab jobs wiki_dev, wiki_prod, phpdoc_dev, phpdoc_prod on forks
If a developer incorrectly codes directly on their fork's develop branch and then creates a merge request, the pipelines will fail and they will be unable to resolve it and break their origin develop branch.
This is because the pipelines will try to run wiki_dev & phpdoc_dev. These will fail, because they do not have the correct CI variables, nor do we want to release these into the wild, because it is a security risk and will cause all merge requests to deploy directly to dev.wiki and dev.phpdoc.
Add rules to wiki_dev, wiki_prod, phpdoc_dev, phpdoc_prod to account for this use case and prevent the jobs for running.
