Changed all references of processable_image to processable_file which was a breaking change from v1 to v2 https://github.com/igorkasyanchuk/active_storage_validations/tree/3.0.2?tab=readme-ov-file#upgrading-from-1x-to-2x
Also it upgraded the way of validating files from just the file name and content type, so tests also needed to change for file upload checks
Refactored all the similar file image validator content type in Spree::Image::ACCEPTED_CONTENT_TYPES and Updated ImageBuilder.import method to use the url.path when getting filename.
