Add eslint warning if console.log are left

[antgamdia]

Description of the change

Minor PR adding just an eslint warning if the committed code includes unnoticed console.log. I thought it was enabled by default, but some previous updates in the eslint config must have disabled it.

Benefits

I won't commit again (or at least, our CI won't let it pass) code with console.log eventually useful for debugging a unit test :P

Possible drawbacks

N/A

Applicable issues

N/A

Additional information

I'd say it was marked (in the past) as an error, which prevented eventual console statements when developing, Now it is a warning, we should be able to run yarn start without any issues.

Great, thanks.
