[antoyo]

Maybe we could use job summaries to provide a summary of the number of passing tests in the failing CI jobs as well as showing the failing jobs that should pass:

• https://docs.github.com/en/actions/using-workflows/workflow-commands-for-github-actions#adding-a-job-summary

Maybe we could group failing jobs together. See this:
