Use new hook Minz_HookType::ActionExecute for extending actions

[Inverle]

Solves the issue described in this TODO:

Extensions/xExtension-Captcha/Controllers/authController.php

Lines 4 to 6 in fae05cf

	// TODO: Use another approach than class inheritance to allow multiple extensions to work with the same controller.
	// phpcs:ignore Generic.Classes.DuplicateClassName.Found
	class FreshExtension_auth_Controller extends FreshRSS_auth_Controller {

Depends on FreshRSS/FreshRSS#8599 and FreshRSS/FreshRSS#8600
now merged
