@marianunez I'll review this PR which adds Korean language support to the Mattermost Boards plugin. The changes appear to include:

• Translation updates in webapp/i18n/ko.json
• Korean language registration in webapp/src/i18n.tsx and webapp/src/constants.ts

I can see from the screenshot that Korean (한국어) is now available in the language selector and the UI is displaying Korean translations. Let me conduct a comprehensive review of the implementation.
