Auth cookie persistence

[raky291]

Is there an example of how I can implement the new COOKIE option in the Persistence interface? #8839

Official reference docs: https://firebase.google.com/docs/reference/js/auth.persistence

@raky291 To use browserSessionPersistence or others with the new tree-shakable API:

import { initializeAuth, browserLocalPersistence } from ''firebase/auth'';

const auth = initializeAuth(app, {
  persistence: browserLocalPersistence
});

The COOKIE persistence mentioned in some server-side docs usually refers to next-firebase-auth patterns or using cookies for session management (minting a session cookie), rather than client-SDK state persistence which defaults to IDB/Local.
