In order to make product verification possible, we want to have a test system showing the latest state of our Query Builder.
Acceptance criteria:
- The query builder gets a tool on toolforge https://toolsadmin.wikimedia.org/tools/id/query-builder-test
- The query builder is accessible via https://query-builder-test.toolforge.org/
- The repository is pulled automatically, either periodically or on merge, and then rebuilt for the web server
