Pull Request resolved: https://github.com/facebook/react-forget/pull/2854
Adds a toy next.js app which doesn't do anything interesting. It has a single
e2e test which can be run via `npm run test:e2e`, which checks if a `$` variable
was injected by the compiler, as a sanity check whenever we commit a new version
of the compiler to the external repo.
Sorry about the thrash in advance! This removes the top level `forget` directory
which adds unnecessary nesting to our repo
Hopefully everything still works
