Related Issue

• Responding to new repository for static icon asset #2229

Summary

• 피그마 플러그인에 의해 만들어진 icons.json에 따라 아이콘 svg파일을 만드는 스텝을 액션에서 제거합니다.

Details

• Change repository to bezier-asset where figma plugin creates PR  #2357 에서 피그마 플러그인이 바라보는 레포가 bezier-react에서 bezier-asset으로 변경되면 bezier-react에서는 icons.json파일이 만들어지지 않고 아이콘 파일이 직접 생성되게 됩니다. (e.g. Icon update PR made by bezier-asset main #2356)
• 이에 따라 기존의 generate-icon-files.yml 에서 icons.json파일 관련 스텝을 없애고 액션 이름을 변경합니다.

Breaking change? (Yes/No)

• No
