Why are request cookie values typed as string | string[] instead of just string?

[ezzatron]

To clarify, this is an MSW 2 question, and I'm specifically talking about the cookies property of the handler info object when using http (probably graphql too), like so:

import { http } from "msw";

export const handlers = [
  http.get("/", ({ cookies }) => {
    // `cookies` has type `Record<string,string|string[]>`
  })
]

I could be misunderstanding something, but I can't think of a circumstance where cookie values make sense to represent with an array? It's extra weird, since there are other places in the code where MSW represents cookies with Record<string,string> 🤔

Hey, @ezzatron. Thanks for raising this. I believe this is a bug in types. While response cookies may have multi-value cookies, like Set-Cookie, request cookies are always a flat [string]: string map.

Would you like to open a pull request to fix this?

Sure! I'll take a look.
