Ability to configure favicon for universal login branding customization

Feature: configure favicon for universal login branding customization.

Description: All branding related configurations for universal login page is done using no code tool or Auth0 management console. But setting the favicon url requires Auth0 Management API (Auth0 Management API v2).

It would be better to have favicon URL configurable in Branding → Universal Login → Customization.

Use-case: We are building a SaaS app and we are using Auth0 universal login page.
