[dopry]

Describe the bug
inngest.send() SendEventPayload typing does not include a "user" property per https://www.inngest.com/docs/reference/typescript/v4/events/send

To Reproduce
Steps to reproduce the behavior:

1. Create a function with

 const inngest = new Inngest({ id: 'example' });
 const result = await inngest.send({
      name: "eventName",
      data,
      user: {
        external_id: "sub",
        email: "email",
        name: "name",
      },
    });

Expected behavior
there are no TS errors for "user".

System info (please complete the following information):

• npm package Version 4.5.1, sil applies to latest
• Framework: Next.js
• Platform local development

Additional context
Here is the type tree for reference

export interface MinimalEventPayload<TData = any> {
  id?: string;
  data?: TData;
  v?: string;
  meta?: EventMeta;
}
export interface EventPayload<TData = any> extends MinimalEventPayload<TData> {
  name: string;
  ts?: number;
}
export type SendEventPayload = SingleOrArray<PartialK<Omit<EventPayload, "v">, "ts">>;

This was an intentional change. We added it to our v4 migration guide:
https://www.inngest.com/docs/reference/typescript/v4/migrations/v3-to-v4#remove-event-user

Sorry for missing that in the migration guide

cool, so it sounds like the v4 docs needs to be updated to reflect the change.
