PdfFormat route \Drupal::routeMatch()

Problem/Motivation

PdfFormat::getOutput() gets the entity from the route. But, $this->entity already exists. The routeMatch is unnecessary.

Steps to reproduce

$printable = \Drupal::service('printable.controller');
$node = \Drupal::service('entity_type.manager')->getStorage('node')->load(1);

$file = $printable->getOutput($node, 'pdf', []);

// $file will be the full path to the file

Proposed resolution

      $entity_type = $this->entity->getEntityTypeId();
      $pdf_location = $token_service->replace($pdf_location, [$entity_type => $this->entity]);
