docs: guide example page translated into Korean

[Gaic4o]

I have translated the Guide page into Korean.

If you think there are aspects that need improvement, please let me know, and I would be happy to make the adjustments. Thank you!

I have requested a Korean translation review from one reviewer in the FSD Discord Korean community to ensure that my Korean writing is well done. I would appreciate it if you could merge it after the review is completed.
