Configure permitted parameters for Devise in ApplicationController

•Created a method update_allowed_parameters in ApplicationController to configure permitted parameters for Devise.
•Added a before_action callback to invoke the update_allowed_parameters method before any Devise controller action.
•In the update_allowed_parameters method, used devise_parameter_sanitizer.permit to specify the permitted parameters for sign-up and account update actions.
•For sign-up, permitted the name, email, and password attributes.
•For account update, permitted the name, email, password, and current_password attributes.
