Bundle Product Form Fixed With Clearer Product Selection UX

We identified a regression in the bundle flow where the new product form could not render the product type field in the UI when adding a product to a bundle. This has now been fixed.

In addition, we have improved the UX of the dialog used while adding products to a bundle to make the flow clearer.

It is now more obvious how to add an existing product to the bundle or create a new product within the bundle flow.
