fix(i18n): migrate Korean to correct ISO code 'ko'

[yslpn]

i18n: Migrate Korean to ko, deprecate kr

• Use the correct ISO 639-1 language code for Korean: ko
• Keep kr as a deprecated alias for backward compatibility
• Add ko to build scripts (npm & JSR); preserve kr outputs
• Update types and documentation accordingly
• No breaking changes in this release; kr will be removed in a future major

Migration: prefer @valibot/i18n/ko instead of @valibot/i18n/kr.

Closes #1285

Pull Request Overview

This PR migrates Korean language support from the incorrect ISO code 'kr' to the correct ISO 639-1 code 'ko' while maintaining backward compatibility.

• Adds proper 'ko' language code support with complete Korean translations
• Deprecates 'kr' with a JSDoc comment and keeps it as an alias for backward compatibility
• Updates build scripts, package exports, and documentation to include both codes

I haven't forgotten this PR and will probably merge it in 1 to 2 weeks. I am currently focused on Formisch a few other things.
