GraphQL Modules and Apollo Server 4 Example

This is to demonstrate the incompatibility (and a workaround) for using Apollo Server 4 and graphql-modules together. Reported to graphql-modules here

npm install
npm start

results in...

.../graphql-modules-apollo-4/node_modules/@apollo/server/dist/cjs/utils/schemaManager.js:68
            throw new Error('You must call start() before getSchemaDerivedData()');
                  ^
