Could you confirm if we need the config_overrides.js file?

Discussing with @VictorVelarde a couple days ago it seemed it was only useful to library/template developers. If that's the case, we should remove this file as well.

@borja-munoz config-overrides.js is necessary if you want to work with carto-react linked in your project.

We can land this as it is, as it's 100% clear, and discuss about config-overrides.js in the channel / another PR
