Description of the issue

Google Pay doesn't show shipping rates from the Distance Rate Shipping extension. However, the rates do return on the Checkout page and Apple Pay correctly.

Steps to replicate

1. Enable digital wallets option
2. Install and set up Distance Rate Shipping
3. Create a Distance rate under WooCommerce > Settings > Shipping
4. Add a product to cart and go to Checkout. Enter a shipping address, observe how the rate is returned on the Checkout page and Apple Pay, but not Google Pay
