[WEB-1857] Use correct shipping location for checkout

[shubha-rajan]

📲 What

Use the location id from selectedShippingRule instead of project when calling createCheckoutInput.

🤔 Why

Some pledges in production had a shipping location set to a city or town (they should be set to a country) and that the incorrect shipping location matched the project location.

👀 See

The bug (user selected US Shipping, which is $30, no bonus support):


Jira

✅ Acceptance criteria

• Late pledge a project on staging and select a shipping location that is different from the project location
• Verify that the location of the created checkout and backing match the location selected in the previous step.
