South Korea Zip Code Validation incorrect

[wigman]

Issue

Zip code validation fails on adresses from South Korea since it validates against deprecated format.
Current validation is 123-456. This should be 12345.

"Postal codes in South Korea are 5-digit numeric, whose system newly introduced in August 1, 2015." (https://en.wikipedia.org/wiki/List_of_postal_codes_in_South_Korea)

Preconditions

On all 2.* versions including development branch.

Steps to reproduce

go to cart or checkout, select South Korea and insert postal code 12345

Expected result

Validation should succeed.

Actual result

Validation fails

Solution

Replace:
<zip countryCode="KR"> <codes> <code id="pattern_1" active="true" example="123-456">^[0-9]{3}-[0-9]{3}$</code> </codes> </zip>
With:
<zip countryCode="KR"> <codes> <code id="pattern_1" active="true" example="12345">^[0-9]{5}$</code> </codes> </zip>
OR add it as a second pattern (for backwards compatibility ?)

in /app/code/Magento/Directory/etc/zip_codes.xml
