demo中没有1.3.4的低代码引擎主包路径

官方demo中, index.ejs文件中低代码引擎主包和页面框架样式版本为1.3.3-beta.0

可以更新到的最新版本是1.3.3-beta.3

npm当前发布的最新版是1.3.4

官方的https://uipaas-assets.com/一直没有1.3.4的CDN加速?

```




```

Start with the demo's index.ejs and inspect the referenced @alilc/lowcode-engine CDN URLs. Check whether version 1.3.4 is available at the stated asset path; done means the demo references the available current version consistently for both engine-core.css and engine-core.js.
