What is the current behavior?

The authentication tutorial example in the documentation contains smart quotes (“ and ”) instead of standard ASCII quotes ("), which causes a TypeScript syntax error in code editors and sandpack previews.

What is the new behavior?

Replaced the smart quotes with standard double quotes to ensure the code compiles correctly and behaves as expected.

- name: “Error”,
+ name: "Error",

Fixes #6814
