feat: generate api

[pyphilia]

This is a draft-test for api generation. How I can see it can work:

1. yarn openapi-ts will generate src/client with api and types. It uses a link/path from openapi-ts.config.ts. This link could be api.graasp.org/docs/json, or probably localhost:3000/docs/json. If you really want it could be a static file. src/client would be git-ignored.
2. On test and build, run openapi-ts to get the client. I used it on a partial schema, so it was quick. I hope it stays quick.

I think @graasp/query-client should provide the config, because it can be tweak with templates to get exactly what we need.

Needed steps detected:

• improve schema: add error types (currently result to unknown)

To investigate:

• generate cypress server?

We need to encapsulate in body, I think it's good as it is clear why the props are used.
