MDVA-32012 patch: S. Korean and Argentina zip codes validation

The MDVA-32012 patch solves the issue where Argentine and South Korean zip codes are not validating, due to changes or variation in national postal code formats. South Korean zip codes are now required to be 5-digits, whereas previously they were 6-digits. Argentine zip codes can be both numeric and alphanumeric. The MDVA-32012 patch means that these formats for postal code values will validate for these countries. This patch is available when the Quality Patches Tool (QPT) 1.0.9 is installed. Please note that the issue is scheduled to be fixed in Adobe Commerce version 2.4.2.

Inputting a 5-digit South Korean or alphanumeric Argentine zip codes produces a warning:

Provided Zip/Postal Code seems to be invalid. Example: [1234 (if inputted an alphanumeric Argentine address)] or [123-456 (if inputted a 5-digit South Korean address)]. If you believe it is the right one you can ignore this notice.

Steps to reproduce:

  1. Open the storefront.
  2. Add item to cart.
  3. Process to checkout.
  4. Add a new address with South Korea for the country and input a 5-digit zip code or add a new address with Argentina for the country and input an alphanumeric zip code.
  5. Try to save.

Expected results:

Address should save without warning.

Actual results:

Saving address returns warning.
