[Styled-components] it looks like an unknown prop "X" is being sent through to the DOM 오류 해결 (X: 사용자 정의)

styled-components: it looks like an unknown prop "backgroundcolor" is being sent through to the DOM, which will likely trigger a React console error. If you would like automatic filtering of unknown props, you can opt-into that behavior via `<StyleSheetManager shouldForwardProp={...}>` (connect an API like `@emotion/is-prop-valid`) or consider using transient props (`$` prefix for automatic filtering.)
