./scripts/lib/phpstan/dummy-classes.php contains:

namespace Drupal\webhook_receiver {
  class WebhookReceiver {
    public function webhooks() {
      return [];
    }
  }
  class WebhookReceiverPluginBase {}
}

Yet when I remove:

    - */eventbrite_one_way_sync/src/Plugin/WebhookReceiverPlugin/Eventbrite.php

from ./scripts/lib/phpstan/phpstan.neon

I get the error:
