Description: 

UpdateRegistry now expects a MemoryCacheInterface as the 6th parameter.

Before:

public function __construct(
    protected $root,
    protected $sitePath,
    array $module_list,
    protected KeyValueStoreInterface $keyValue,
    ThemeHandlerInterface $theme_handler,
    protected string $updateType = 'post_update',
  )

After:


public function __construct(
    protected $root,
    protected $sitePath,
    array $module_list,
    protected KeyValueStoreInterface $keyValue,
    ThemeHandlerInterface $theme_handler,
    MemoryCacheInterface|string|null $memoryCache = NULL,
    protected string $updateType = 'post_update',
  )

This change likely only affects Drush or similar projects that directly interact with the update system functionality.
