Nyc does not work with Bun / `process.binding("spawn_sync")` is not implemented

[ygrandgirard]

What version of Bun is running?

1.0.26

What platform is your computer?

Microsoft Windows NT 10.0.22631.0 x64

What steps can reproduce the bug?

• Create a new bun project with bun init,
• Install nyc from npm with bun add nyc,
• index.ts :

  export function ok(): boolean {
  return true;
  }

• index.spec.ts :

  
  import { expect, test } from 'bun:test';
  import { ok } from '.';

test('ok', () => { expect(ok()).toBe(true); });

* `package.json` :
```typescript
{
  "name": "bun-nyc",
  "module": "index.ts",
  "type": "module",
  "scripts": {
    "test": "nyc bun test"
  },
  "devDependencies": {
    "@types/bun": "latest"
  },
  "peerDependencies": {
    "typescript": "^5.0.0"
  },
  "dependencies": {
    "nyc": "^15.1.0"
  }
}

What is the expected behavior?

Run nyc, and do whatever it is supposed to do.

What do you see instead?

$ nyc bun test
process.binding("spawn_sync") is not implemented in Bun. If that breaks something, please file an issue and include a reproducible code sample.
error: script "test" exited with code 1

Additional information

An issue was filled for the same bug back in September. It was closed as completed by its author the same day for some reason.

this can be implemented semi-easily in BunProcess.cpp, where the spawn_sync binding contains an object with a spawn function that points to a JS function that calls Bun.spawnSync, and remaps the output as node does. was going to add the good first issue tag but its not the most clear thing possible.
