GraphQL generators

[kasparszarinovs]

Look into the following options, and how they work with Prisma.

1. GraphQL code generator. This is currently used in Oops returns back-end project. It is a schema first approach and generates resolvers, inputs, etc. from the GraphQL schema.

2. TypegraphQL with a Prisma generator. Unlike previous, this is a code-first approach.

Both solutions will work with Apollo server.
