move related products above product description

You may want to try this plugin – https://woocommerce.com/products/product-description-on-shop-page/

Their description says it can show description for the related products.

Your wish could be realized in many ways:

• Customize the template of the product detail page. To do this, you need a child theme and have to customize the template for yourself. See: https://developer.www.ads-software.com/themes/advanced-topics/child-themes/
• You could also customize the order of the HTML boxes in the template with a pure style solution. An example of this would be here: https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_flexible_box_layout/Ordering_flex_items
• You can also contact the support of the theme you are using and ask if they have a suitable faster solution at hand: https://www.ads-software.com/support/theme/storefront/
• Depending on the structure of the template, hooks from WooCommerce could also help to change the order of the sections. This overview may be helpful here: https://www.businessbloomer.com/woocommerce-visual-hook-guide-single-product-page/
• You can also look for someone to help you with the customization. You can find someone like this here: https://jobs.wordpress.net

Side note to @tashalong Could you please stop putting your “Fixing WordPress” topics in “Developing with WordPress”? I moved like 2 years of topics from the wrong forum to the correct one.

Not one of your topics are for Developing with WordPress. They are either general problem or plugin/theme specific.

General WordPress is “Fixing WordPress”. So please use that forum, your local forum moderator will thank you. ??
