🐛defineSiteConfig中title的颜色似乎使用unocss定义了，无法响应themeConfig中的color的选择

[Crpto999]

Describe the bug

const classes = ref('site-name text-lg leading-loose bg-gradient-to-r gradient-text from-#1e3c72 to-dark dark:(from-#66a6ff to-blue-500)')

不优雅~

另外似乎 banner的enable配置项不能工作，云佬2年前使用v-if修复过这个问题， 但是现在的版本似乎去掉了v-if这里的修复？
