User @mentions don't render when coming through the notion integration API

Description

We are using the compat transformer with the new Notion API to embed private Notion docs. The API is not returning the user data, so instead of the block trying to render the username (which is available on the block) it renders nothing in place of these private user @mentions.

I believe it is this line here that is short circuiting: https://github.com/NotionX/react-notion-x/blob/cfbfcc15145d9ece96d2fa526b5c4f8305576c99/packages/react-notion-x/src/components/text.tsx#L69

Notion Test Page ID

The problem is inherently related to private pages.
