lib.dom missing "duplex" option in RequestInit

Suggestion

🔍 Search Terms

I looked for "lib.dom RequestInit duplex".

✅ Viability Checklist

My suggestion meets these guidelines:

• This wouldn't be a breaking change in existing TypeScript/JavaScript code
• This wouldn't change the runtime behavior of existing JavaScript code
• This could be implemented without emitting different JS based on the types of the expressions
• This isn't a runtime feature (e.g. library functionality, non-ECMAScript syntax with JavaScript output, new syntax sugar for JS, etc.)
• This feature would agree with the rest of TypeScript's Design Goals.

⭐ Suggestion

The RequestInit type in lib.dom seems to be missing the duplex option. See nodejs/node#46221 for further details.

📃 Motivating Example

nodejs/node#46221 has an example.
