Skip jobs when triggering updates to speed up the process

When clicking the new update links generated by the dashboard eveything gets recomputed from scratch: this means that we waste resources but more importantly we slow down the developers who triggered the updates.

To avoid that, point the pipeline triggering the updates to the previously computed data and skip the jobs that are now superfluous.

• Normal pipeline: https://gitlab.apertis.org/infrastructure/dashboard/-/pipelines/190111
• Test pipeline with skipped jobs: https://gitlab.apertis.org/infrastructure/dashboard/-/pipelines/190099
