CRA@3: Eject warning message references CRA2

[petetnt]

The warning message links to the CRA2 release blog post, but we probably want to link some page in the docs (eg. extended https://facebook.github.io/create-react-app/docs/alternatives-to-ejecting) where these things are explained briefly.

create-react-app/packages/react-scripts/scripts/eject.js

Lines 57 to 63 in dc133a3
