[KO] Translation improvement for "{days}" usage

Hi team,

While contributing to [https://github.com/microsoft/ai-agents-for-beginners]
(https://github.com/microsoft/ai-agents-for-beginners)
I found that the current Korean translation for "Excluding {days}" is slightly unnatural.

Current: "{days} 제외하고"
Suggested: "{days}를 제외하고"

The added particle "를" makes the sentence grammatically correct in Korean.

Since co-op-translator is being used for localisation, I’d like to propose this improvement here as well.

Thanks!

Search the repository for the exact Korean phrase "{days} 제외하고" and identify the localization source or generated file containing it. Replace it with "{days}를 제외하고" and verify that the Korean translation uses the suggested grammatically correct wording.
