Readme document object InferType doesn't work as documented.

To Reproduce Those code just shown in readme.md:

const userSchema = object({
  name: string().required(),
  age: number().required().positive().integer(),
  email: string().email(),
  website: string().url().nullable(),
  createdOn: date().default(() => new Date()),
});

type User = InferType<typeof userSchema>;
/* {
  name: string;
  age: number;
  email?: string | undefined
  website?: string | null | undefined
  createdOn: Date
}*/

But in vscode extension ms-vscode.vscode-typescript-next I just got this type for User (when I hover my mouse on it):

type User = {
    name?: string;
    age?: number;
    email?: string;
    website?: string;
    createdOn?: Date;
}

I have tried typescript@4.7 for older version of NonNullable and then noticed that typescript: "^4.9" was using in current yup's devDependencies. And I switch to that version, using vscode command Select Typescript Version to select the workspace typescript sdk. Successfully switching to the specific version, but it still doesn't work.

Expected behavior Just as documented, get an non optional object key inference.

Platform (please complete the following information):

MacOS 14.2.1
NodeJS 18.16.0
yup 1.3.3
Typescript 4.7 、4.9、5.4 （all tried）
visual studio code 1.85.2
vscode plugin ms-vscode.vscode-typescript-next 5.4

Additional context I have searched but amazingly found that few issue about this issue described.
