Show CI failure details to non-collaborator PR authors

[efekrskl]

What is the problem this feature will solve?

CI is now only visible to collaborators. External contributors can see that CI failed, but not why, so they have to ask a collaborator to learn about the CI status.

What is the feature you are proposing to solve the problem?

If CI fails on a PR from a non-collaborator, have nodejs-github-bot post a short comment with the failure summary, failing test names etc.

Original idea by @RafaelGSS

This is also similar in spirit to #32306 from 6 years ago, but opening a new issue to bring visibility to this in light of the recent collaborator-only CI access change.

What alternatives have you considered?

• Ping a collaborator
• Write bug free code 🧠

Hey, I can make sure the bot shares CI failure details with non-collaborators so they don't have to ask for help.
Can you assign me this issue?

Thanks

Thanks for your interest @Mahnoor-Zaffar, we don't assign issues so feel free to work on this.

That being said, since you have no Jenkins access, this might be a bit tricky to get done. However, I'm just guessing

[Mahnoor-Zaffar]

Yeah, it is getting trickier as I get more into it

Hey team! Any news on this? This would indeed be super helpful for (new) contributors like myself in #64682 to see whether the potential failures are linked to the PR or if it's coming from something else (known error, flaky test).
