[nikgraf]

Sebastian mentioned they are not necessary anymore.

    "paths": {
      "@graphprotocol/hypergraph": ["./packages/hypergraph/src/index.js"],
      "@graphprotocol/hypergraph/*": ["./packages/hypergraph/src/*.js"],
      "@graphprotocol/hypergraph-react": ["./packages/hypergraph-react/src/index.js"],
      "@graphprotocol/hypergraph-react/*": ["./packages/hypergraph-react/src/*.js"]
    },
