[Enhancement] support animated Backgroundimages
To support animated Backgroundimages like wepb the original public url is needed. Support animated Backgroundimages is possible by using original public url if adaptiveImages is disabled
In RenderBackgroundViewHelper on line 134 (with adaptiveImages disabled) instead of $processedFile using $fileObject->getPublicUrl() because $processedFile processes the original e.g. webp to png and loosing the "animation"
