Drupal 10: Class "Symfony\Component\EventDispatcher\Event" not found

Problem/Motivation

_Error_: Class "Symfony\Component\EventDispatcher\Event" not found in _include()_ (line _13_ of _/var/www/html/web/modules/contrib/commerce_wishlist/src/Event/WishlistEvent.php_).

Steps to reproduce

- Install module, enable `Show wishlist button` for `Add to cart form` on `Manage display` tab of product type
- Navigate to product page, add item to wishlist using `Add to Wishlist` button
- Check for error in recent log messages

Proposed resolution

Replace Symfony\Component\EventDispatcher\Event with Drupal\Component\EventDispatcher\Event, refactor EventDispatcher::dispatch() argument order
