Incorrect href in React learning documentation

https://ko.react.dev/learn/updating-arrays-in-state#making-other-changes-to-an-array

On the above page, the href attribute for '중첩된 JavaScript 객체 업데이트' is incorrect.
It should be corrected to https://ko.react.dev/learn/updating-objects-in-state#updating-a-nested-object.

The translated learning documentation has helped me a lot in my learning.
Thank you.
