src/ReactDOMRe.mlast.d and src/ReactDOMRe.cmj aren't in the downloaded reason-react module and require a build

Reason-react is missing two files that need to be produced by bsb -make-world else the app throws errors.

This is problematic in my use case of deploying my reason-react app to Google App Engine (Standard environment), where one can only push built code and App Engine does the install step. A postinstall script isn't viable: it supports a gcp-build script that will run after install, but looking at the logs it will delete node_modules and reinstall with the --production flag, so the created files would be deleted anyway.

Example (given no node_modules directory):

$ yarn install --prod                                                                                      
yarn install v1.13.0

ReactDOMRe seems to be the only package where this happens. Is this intentional? Is it common practice to require a dependency to go through this build step?
