Dynamic properties are deprecated PHP 8.2, explicitly declare WizardFormController::$wizardFactory

Problem/Motivation

When running tests that rely on ctools in PHP 8.2, deprecation errors are thrown like:

Exception: Deprecated function: Creation of dynamic property Drupal\ctools\Controller\WizardFormController::$wizardFactory is deprecated
Drupal\ctools\Controller\WizardFormController->__construct()() (Line: 48)

Proposed resolution

It is possible to alleviate these deprecation errors by adding #[\AllowDynamicProperties] before the class declaration, but in this case it may make more sense to explicitly declare $wizardFactory as a public property instead.
