Add purchase options card extensions

[JulienHe]

Background

Closes https://github.com/Shopify/subscriptions-app-remix/issues/1642, shipping for 2025-01, but will make it on unstable mid-october

Adding the UI extension action for the purchase options card in the product page and product variant page.
The extension target are named:

• admin.product-purchase-option.action.render
• admin.product-variant-purchase-option.action.render

This should be release as the same as we are releasing our new extensions by enabling our beta flag.

We do also have a PR for the documentation of these targets.

I think you will want to extend ActionExtensionApi here, or just add the close method from that type (I forget if extends can override a property, in this case data.

Correct, changed.

I think we have to wait to merge this until the 2024-10 branch has been created

Nit: should we show a puzzlify header to match the other screenshots in this page?

[JulienHe]

Sure, will change that 👍
