MissingMandatoryParametersException is not caught in redirect_entity_delete

After replicating the issue, I can confirm that Patch #2 resolves the issue satisfactorily. Additionally, I've introduced an alternative method to handle straightforward exceptions, which has proven effective in addressing the problem in my scenario.

function redirect_entity_delete(EntityInterface $entity) {
  try {
    if ($entity->getEntityType()->hasLinkTemplate('canonical') && $entity->toUrl('canonical')->isRouted()) {

       // Generate the canonical URL after setting the required parameters.
       $canonical_url = $entity->toUrl('canonical');
      
       // Check if the canonical URL has the required parameters set.
      try {
        if ($canonical_url->getRouteParameters()) {
          redirect_delete_by_path('internal:/' . $entity->toUrl('canonical')->getInternalPath());
        }
      }
      catch (Exception $e) {
        // This can happen if some mandatory parameters are missing.
      }
      redirect_delete_by_path('entity:' . $entity->getEntityTypeId() . '/' . $entity->id());
    }
  }
  catch (RouteNotFoundException $e) {
    // This can happen if a module incorrectly defines a link template, ignore
    // such errors.
  }
}

Not sure what extra testing we want to do here. I tested this coming from 🐛 Error when removing a menu Needs work and it solved the problem perfectly.

Merged.
