🎨 팔레트: [UX 개선] 브라우저 번역 호환성을 위한 nav 요소 접근성 레이블 방식 개선

[seonghobae]

💡 내용: nav 요소의 접근성 이름을 aria-label 속성 대신 aria-labelledby와 시각적으로 숨겨진 h2 요소 쌍으로 변경했습니다.
🎯 이유: 브라우저 번역 도구(Chrome Translate 등)는 종종 태그의 속성인 aria-label을 번역하지 않고 무시합니다. 다국어 환경에서 스크린 리더 사용자의 접근성을 향상하기 위해, 번역기가 텍스트로 인식할 수 있는 실제 HTML 요소를 활용하여 레이블을 제공하도록 수정했습니다.
📸 변경 전/후: (시각적 변경 없음 - 스크린 리더 및 번역 도구 동작만 개선됨)
♿ 접근성: 문서의 언어가 변경될 때 내비게이션 랜드마크의 이름도 적절히 번역되어 스크린 리더에서 올바른 언어로 안내되도록 개선되었습니다.
