Pushed a commit disabling max-len eslint rule as well. With prettier handling it, I don't really see why we should litter the code base with disables for strings, comments, and regexps. Can remove (or move to another PR) if you want, of course 😄

Seems like this one conflicts with pretty much everything, so we'll need to redo this PR :(

[SimenB]

I can redo it 😄

Seems like max-len stuff was done in #3444

[cpojer]

Woohoo, thanks!
