Fix WooCommerce Variation Alt Text for SEO & Accessibility

WooCommerce variable products often have separate images per variation, but alt text is rarely set for these images, leaving them invisible to search engines and screen readers. A store with 200 variable products and five variations each could have 1,000 images missing alt text. Good alt text should name the variation attribute (e.g., color) and include relevant visual details to improve both accessibility and SEO.
