Things that need to be done to consider the move to Gerrit complete:
* [x] create Query Builder Gerrit repo -> https://wikitech.wikimedia.org/wiki/Gerrit#Creating_new_repositories
* https://gerrit.wikimedia.org/r/admin/repos/wikidata/query-builder
* [ ] somehow figure out Cypress in CI (see T230729 for some prior work) and branch hosting, if needed
** have a look at https://github.com/wikimedia/integration-config/blob/master/dockerfiles/node10-test-browser/run-with-xvfb.sh
** waiting on the server to be ready for cypress: https://docs.cypress.io/guides/continuous-integration/introduction.html#Boot-your-server
* [ ] create Jenkins test-job, it needs docker with nodejs? -> query service ui
** https://gerrit.wikimedia.org/r/c/integration/config/+/668040
** https://gerrit.wikimedia.org/r/c/integration/config/+/667623
** https://gerrit.wikimedia.org/r/c/integration/config/+/668069
* [ ] create Jenkins merge job?
* [ ] adjust translate-wiki to add their translations to the Gerrit repo
* [ ] create mirror to https://github.com/wikimedia/query-builder/
* [ ] delete repo at https://github.com/wmde/query-builder/
* [ ] manually fix test-system to pull from Gerrit/gittiles instead of GitHub (though it could pull from the mirror)
* Alternatively: can Jenkins push after merge to toolforge and trigger the build script there? That would then be real CD for our CI... 馃ズ
