Provide options to add Simple Sitemap files to robot.txt

@gxleano, I think import of RequestStack should be "use Symfony\Component\HttpFoundation\RequestStack;" and not "use Drupal\Core\Http\RequestStack;"

Works for me after on D10 !

Anna D → made their first commit to this issue’s fork.

Agreed with #19. Replaced deprecated Drupal\Core\Http\RequestStack with Symfony\Component\HttpFoundation\RequestStack.

Tested with Drupal 10.1.5

Thanks @anna-d to take care of that, really appreciate it.

Would be great to have this feature on next releases @ccjjmartin.

Sorry to bother, but can we merge this one too? :)
