Add credentials: include and Cookie header to prevent 401 error

[yinkiu602]

Description

When connecting to a gradio app with authentication using JS client, there will be 401 error when interacting with the API.

When running it locally with the JS client:

When running it on browser (Chrome) by including it via CDN (as mentioned in the documentation) with the following code:

It shows 401 error with message "Not authenticated".


Which by looking an the request headers, the credential cookies are not being sent as part of the request:

This PR propose the change to add the required headers (credentials: "include" & Cookie) when Client.stream() is being called.
Headers and Credentials are both being added as running the code files in terminal with credentials: "include" only will also result in 401 error. While running it in browser with Cookie header only will also result in 401, Adding both headers will give the best compatibility when using the client on different platform.

Reproduction

import { Client } from "@gradio/client";

const client = await Client.connect("yinkiu602/testsetsetsets", {auth: ["admin", "pass1234"]});
const result = await client.predict("/chat", { 		
    message: "Hello!!", 		
    system_message: "Hello!!", 		
    max_tokens: 1, 		
    temperature: 0.1, 		
    top_p: 0.1,
})

console.log(result.data);

It should fail with 401 error. By changing the stream function, it should work normally.

Looks good to me! Thanks @yinkiu602. Note, I'd like to know if @pngwn is happy with this since he's more familiar with the stream logic

edit: got the ok from @pngwn
