Steps to reproduce

yarn node build.js

What is expected?

props的type属性是可选的，导致生成dts文件时报错

What is actually happening?

将withDefaults.vue编译成withDefaults.ts后，props的type属性的类型应该不是可选的

Could you describe the error in more detail?

Use withDefaults to define attributes in script setup, and the type inference is incorrect after compile-sfc is compiled into ts file.

in sfc file in ts file

I think it should not contain optional flags

I have the same problem，Please give me a solution

Here is a reproducible demo with readme.md attached。please check @ygj6
