I just pushed two commits:

1. Update the translated content to use Mintlify syntax for tabs, cards, admonitions, page metadata. Also removed images and image references where they have been removed from English.
2. Propagate the English-language snippets into the Korean snippet directory and update the Korean content to use those snippets instead of using the English snippets directly. This paves the way for them to be translated.

If you are generating this content through scripts, please update the scripts according to these changes.

FYI, the broken links are expected.

• In a fork, there is no Mintlify preview site so we check the PR changes against the production site, docs.wandb.ai. That means that fixes in this PR may show up as broken until it is merged.
• The broken links for the old SDK tags are also a known issue. Those SDK tags were inadvertently deleted over the MLK weekend and I believe that the SDK team is working with GitHub to get them back.
• Broken links to totally external resources like openai.com are probably being rate limited.

If you push this branch directly to the main repo instead of a fork, you will get the PR preview site and the link checking experience will be better.
