Sean Massa 0490a7733b [tests] install root typescript version 4.9.5 and standardize on that version (#9858)
This add a root-level `typescript` version that matches the one used throughout for VS Code (and other IDEs) to use when browsing the code. After this PR merges, you will be able to set VS Code's TypeScript version to match the project's version.

This will remove issues where the IDE says TypeScript compilation is good to go, but `pnpm build` disagrees.

If there's a better way to allow this, please suggest it!

headers

Optional headers: Headers

If set, overwrites the incoming headers to the origin request.

This is useful when you want to pass data between a Middleware and a Serverless or Edge Function.

Example

Add a `x-user-id` header and remove the `Authorization` header
import { rewrite } from '@vercel/edge';
export default async function middleware(request: Request): Promise<Response> {
  const newHeaders = new Headers(request.headers);
  newHeaders.set('x-user-id', 'user_123');
  newHeaders.delete('authorization');
  return rewrite(request.url, {
    request: { headers: newHeaders },
  });
}
