We can't use `apollo-server-env` as a project reference because that requires `composite: true`, and that implies `declaration: true`, which doesn't work for `apollo-server-env` because we need to write our own declaration files for re-exported imports.
This commit also removes `apollo-engine-reporting-protobuf` as a reference, which errored out because it doesn't actually contain any TypeScript code.
