**Motivation**
We want to avoid broken installations of wikibase-docker due to changes to wikidata-query-gui (e.g {T227031}).
**Problem**
Currently, we are pulling wikidata-query-gui master as part of building `latest` image of `wdqs-frontend` in our wikibase-docker bundle (check https://github.com/wmde/wikibase-docker/blob/master/wdqs-frontend/latest/Dockerfile#L7).
If wikidata-query-gui changes in any incompatible way with the current configuration we supply as part of building this image, as seen in {T227031}, then the resulting image might end up being broken.
**Suggested Solution**
To avoid pushingApart from tagging the "latest" image, also tag the current "latest" image on the first day of each month as YYYY-MM. This is not going to guarantee there are no broken images, we should try to avoid pulling upstream into the image and fix it to available versions/tags/commits that we would test and only bump up when neededbut at least there will be a possible downgrade/upgrade path available for people using the image.
**AC**
[ ] Pull specific (known to work) commit instead of master of wikidata-query-gui repo into wdqs-frontend image
[ ] Start versioning wdqs-frontned image and tagging it, keeping older versions/tags available (inspiration can be taken from how wikibase-base or wikibase-bundle image are being tagged and versioned).
Monthly tagged images exist in Docker Hub
