phph 8.2 Error in PushActivitySend.php

Hi @slowflyer

The issue may issue by modifying the code

From

if ($container_or_activity instanceof ActivityInterface) {
      if (isset($this)) {
        $this->process($container_or_activity);
      }
      return;
    }

To

if ($container_or_activity instanceof ActivityInterface) {
    $instance = new static(
      $configuration,
      $plugin_id,
      $plugin_definition,
      $container_or_activity->get('social_pwa.web_push_manager'),
      $container_or_activity->get('config.factory')->get('social_pwa.settings'),
      $container_or_activity->get('logger.factory')->get('activity_send_push')
    );

    $instance->process($container_or_activity);
    return;
  }
