ci: triggered notebooks_exec status depends on child job

Context

• When a new push is done on dev or master, the notebooks_exec job triggers a job inside hwc repo, which basically runs all the notebooks (to test if new api changes don't break the notebooks). The problem is that the status of the triggered (children) job was not mirrored to the parent job, so if the execution failed, we did not have this information inside the parent's pipeline status.

What was done

• Added strategy: depend on notebooks_exec job

Review objectives

• ? assessment of code functionality
• ? assessment of code quality
