fix: Do not override HTML attribute title if already set for Action…

[jbonnier]

If an action has no label but has the HTML attribute already set, it should not be replaced by the action name.

Use case example:

$moveDown = Action::new('moveDown', false, 'fa fa-angle-down')
    ->setHtmlAttributes(['title' => $this->trans('Move Down')])
    ->linkToCrudAction('moveDown')
    ->displayIf(static fn(SortableEntityInterface $entity): bool => $entity->getPosition() < $entityCount - 1)
;
