@cloudflare/wrangler postinstall script does not exit


I have to force exit, and the binary is not linked.

And I modified the script
```js
#!/usr/bin/env node

const why = require('why-is-node-running')
const { install } = require("./binary");

install().then(() => {
setInterval(() => {
console.log('-------');
why()
}, 1000)
})
```

And logs as
```txt
$ node ./install-wrangler.js
Downloading release https://workers.cloudflare.com/get-npm-wrangler-binary/1.7.0/x86_64-apple-darwin
wrangler has been installed!

Commencez par install-wrangler.js et binary.js, puis reproduisez l’installation npm décrite dans le rapport. Vérifiez pourquoi le processus postinstall reste actif et pourquoi le binary n’est pas lié. C’est terminé lorsque l’installation se termine sans nécessiter un Exit forcé et que le binary est lié.
