CI: periodically clean image's registry
Summary
Periodically regenerate container images to use updated snapshots on Gitlab-CI.
Purpose
This will force to regenerate the various images of the distributions that we want to test so we get an updated snapshot on them. Otherwise we might be testing a months old version of them.
A bug in ci-fairy was making the deletion of the images to partially fail. It is fixed in the latest version of ci-fairy, so we need to update the value of templates_sha to pick it.
Also, disable the triage:issues job that, now that scheduled pipelines can work again, was being triggered but fails due to some conflict on Ruby and/or Gem versions.
