Fixes #56316
TODO: Add/modify tests (will do later, just pushing this to validate that this is the way to go for changes like this).
I just added a flag to make a conditional output. Is this the usual way to go with NodeJS @pmarchini ?
About the feature, I'm not sure if everyone will like it like this. Maybe add an opt-in flag to format the errors before the report has finished? (like it was before, but now is opt-in). Or maybe don't add a flag now, and maybe add the opt-in flag later if we receive complaints?
