vue vite sass 报错处理 Sass @import rules are deprecated and will be removed in Dart Sass 3.0.0

原vite.config.ts文件中：

    css: {
      preprocessorOptions: {
        scss: {
          additionalData: '@import "./src/styles/xxx.scss";',
        }
      }
    }

 改为：

    css: {
      preprocessorOptions: {
        scss: {
          additionalData: '@use "./src/styles/xxx.scss" as *;',
        }
      }
    }
