Prints the constraints errors on CI

[arcanis]

What's the problem this PR addresses?

When a constraints fail, we currently print a message suggesting to run yarn constraints to get the full details. However, this doesn't make sense on CI, where the command can't be run.

How did you fix it?

On CI, we now print the error list.

I'm however kinda reconsidering this approach of "run yarn constraints for more details" - if this message is displayed, the user will have to run the command 100% of the time. By this point, why not display the output by default? 🤔
