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

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

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.

You should deduplicate the data.

This PR is still on my list. Sorry for the delay.

@yslpn is attempting to deploy a commit to the Valibot Team on Vercel.

A member of the Team first needs to authorize it.

I will merge it when working on Valibot v1.3 soon.

Korean translations cannot be updated until this PR is merged. (I do not know if Korean translations have some defects)
