@LucaCanali,

Thanks for merging the PR about prometheus and e2e tests in k8s!

ArgoCD currently uses https://github.com/LucaCanali/sparkMeasure as the source repository, but the CI/CD pipeline was originally configured with https://github.com/k8s-school/sparkMeasure because the continuous delivery setup was only available there at the time of the initial pull request.

To fix the CI on the master branch, this needs to be updated to point to the official repository: https://github.com/LucaCanali/sparkMeasure.

Also, this situation could be improved long-term by contributing the CI script directly to the original repository (https://github.com/LucaCanali/sparkMeasure) instead of maintaining it in a fork.

Thanks in advance for merging the necessary changes to help restore CI functionality!
