ProcessItemsAsync exits early when a queued item is missing

[Razchek]

In ItemAddedManager.ProcessItemsAsync (L60), a missing item results in the foreach loop exiting prematurely:

jellyfin-plugin-webhook/Jellyfin.Plugin.Webhook/Notifiers/ItemAddedNotifier/ItemAddedManager.cs

Lines 53 to 61 in d4d6999

	foreach (var (key, container) in currentItems)
	{
	var item = _libraryManager.GetItemById(key);
	if (item is null)
	{
	// Remove item from queue.
	_itemProcessQueue.TryRemove(key, out _);
	return;
	}

Because this is inside a foreach, return exits the entire method, preventing remaining queued items from being processed during the same run.
This likely should be continue; so only the missing item is skipped.

If the early exit is intentional, clarification in a comment would help.

(Edit: The reason I found this was because sometimes I would have to run the webhook notifier multiple times to deliver all new updates, even when the metadata was populated)
