[Forwardport] Fix table rate failing for zip+4 address #17770

Original Pull Request

#18166

Description

Currently when a customer uses an American ZIP+4 postcode, the table rate shipping method fails to return a quote.

Fixed Issues (if relevant)

1. Table rate fail when using ZIP+4 shipping address #17770

Manual testing scenarios

1. Create a Product with weight >= 1.
2. Enable the Table shipping rate
3. Import the rate CSV file:
   Country,Region/State,Zip/Postal Code,Weight (and above),Shipping Price
USA,*,12345,1,2
4. Create a customer on the frontend with a zip code in the format ZIP+4 (ex: 12345-1234).
5. Add Product to your cart
6. Go to checkout

Expected result

1. The table rate shipping method should ignore the extension and appear with a 2$ shipping fee.

Actual result

1. The table rate shipping is not present.

The issue is now fixed. If the customer uses a ZIP+4 code (ex: 12345-1234) in case a rate for an exact match (12345-1234) is not found in the table there will be a fallback check for 12345.
