[5.x] Auto-discovery of event listeners not working

[robdekort]

Bug description

In Alpha 1 and 2 I'm using an Event Listener in app/Listeners/PreventDeletingMounts.php. This Listener prevents users from deleting pages that have a mounted collection on them.

namespace App\Listeners;

use Statamic\Events\EntryDeleting;
use Statamic\Facades\Collection;

class PreventDeletingMounts
{
    /**
     * Handle the event.
     */
    public function handle(EntryDeleting $event): void
    {
        if (Collection::findByMount($event->entry)) {
            throw new \Exception(trans('strings.collection_mounted', ['title' => $event->entry['title']]));
        }
    }
}

In Laravel 10 I had to register this in my EventServiceProvider but in Laravel 11 it's supposed to auto-discover those listeners.

It seems in my case this isn't happening. The listener isn't triggering, nor is it listed when running php artisan event:list.

How to reproduce

1. Create a listener
2. Don't manually register it
3. Run php artisan event:list
