Unable to resolve packages with a duplicate key in package.json

[simon-paris]

A package.json containing a duplicate key works in TS 5 and in other tools. But in TS-go, it causes the package to be unable to be resolved, as if the package.json file didn't exist.

I found this in the wild in several private packages.

To reproduce, the package also needs a non-default "main" property.

Example:

import IORedis from "ioredis";

To force the bug, insert a duplicate property.

{
  "name": "ioredis",
  "name": "ioredis",

src/services/redis-client.ts:1:21 - error TS2307: Cannot find module 'ioredis' or its corresponding type declarations.

1 import IORedis from 'ioredis';

This is probably because we're using Go's new v2 JSON package, which errors on duplicate properties (something that RFC 8259 says is undefined behavior, and RFC 7493 disallows).
