`#duplex` is missing from `RequestInit`

[erunion]

The Fetch WG introduced a new duplex property to RequestInit¹ back in July that undici is now abiding by when making payload requests with a ReadableStream². They have added this new duplex property into their own RequestInit types, but as this is now a part of the core fetch specification it should be included here.

Would this really be as easy to close as only removing this line?

That is correct @haukepribnow

The reason #1729 wasn't merged and we removed this type is that it is only supported by Blink, and in order for a type to be added, it needs to be supported by at least two major browser engines.
