fix: allow the name and icon of the web app to be set independently of that of the bot itself (#5225)

api/controllers/console/app/site.py

             if value is not None:
                 setattr(site, attr_name, value)
 
-                if attr_name == 'title':
-                    app_model.name = value
-                elif attr_name == 'icon':
-                    app_model.icon = value
-                elif attr_name == 'icon_background':
-                    app_model.icon_background = value
-
         db.session.commit()
 
         return site
