Update product-media.liquid

[msyyn]

PR Summary:
XR button for product media now uses "title" as the value of title attribute. This PR changes title value to product title as seen on Shopify's documentation:
https://shopify.dev/themes/product-merchandising/media/support-media#launch-the-display-with-a-button

Why are these changes introduced?
Because it makes sense

What approach did you take?
Common sense

Other considerations

Testing steps/scenarios

• Go to any product page that has 3D model as product media and use browser's inspect element to see if XR button's data-shopify-title attribute equals to product's title instead of "title".

Hello @msyyn 👋

Thanks for taking the time to create this fix and participate in making the theme better 👍

I was just checking the changes and I was wondering if you could also make the same change in the product-thumbnail.liquid file ? 🙂

I can re review when it's done 👍

@msyyn, any update on this PR's merge?

Feel free to merge this fix if you think it makes sense, product thumbnail can be checked by someone else:)
