Implemented version of tutorial (part 1/3)

[daanaea]

See this for reference! Original tutorial is here.

In general, it goes over some things I think we need to incorporate:

• federated architecture [split into subgraphs and supergraphs]
• entities across subgraphs [e.g. a Word and its instance(s) of Variant] – requires working out schemas and resolvers
• connecting server API to frontend on Next.js

Please check it if you have time, should take less than 3 hours!

@daanaea Is the intent of this PR to reset the contents of the repo? Im seeing that you've removed node_modules from version control (which is great), but I notice you also removed index.js and package.json which removes the whole project. Is that what you meant to do?
