Move from mini_magick to vips for ActiveStorage variant processor

	# TEMP: re-enable mini magick until variant syntax is changed to vips in ActiveStorageHelper#image_variant_by_width
	config.active_storage.variant_processor = :mini_magick

# TEMP: re-enable mini magick until variant syntax is changed to vips in ActiveStorageHelper#image_variant_by_width
config.active_storage.variant_processor = :mini_magick

I think the main/only place that needs changing is the image_variant_by_width helper method, which has mini_magick/ImageMagick args in it that need to be changed to vips args.
