fix: fix the ts version selected by the user

[huangmingfu]

• 问题：复现demo
  我在 Vue SFC Playground 发现了一个问题，当我选择了 ts 版本号和 vue 版本号，分享链接出去的时候：
  
  接着通过分享链接打开后，vue 版本号可以正常的选择用户保存的设置，但是 ts 的始终都是 latest：
  
  
• 这个 pr 是修复 ts 版本的选择，我已经在 test/main.ts 测试过，测试代码如下，辛苦审核~

const query = new URLSearchParams(location.search)
const { importMap: builtinImportMap, vueVersion } = useVueImportMap()
vueVersion.value = '3.4.0'
const store = (window.store = useStore(
  {
    builtinImportMap,
    vueVersion,
    showOutput: ref(query.has('so')),
    outputMode: ref((query.get('om') as OutputModes) || 'preview'),
    typescriptVersion: ref('4.9.3')
  },
  location.hash,
))
console.info('store', store)

A member of the Team first needs to authorize it.

Hope to fix the code format npm run format

[huangmingfu]

ok, I've already changed it

[wangcch]

This may be due to version differences.

Please confirm whether to use pnpm@9 install.
Or undo this irrelevant modification. Thanks

🤔 I wonder if typescriptVersion === latest can be ignored ?
By default, all data may have a _tsVersion file.
But the default vueVersion is null.

[huangmingfu]

No, if the ts version is not transmitted, request 404.

const store = (window.store = useStore(
  {
    //  ...
    // typescriptVersion: ref('4.9.3')
  },
  location.hash,
))

My latest submission has solved this problem.

It is similar to the writing of vue version request.

[wangcch]

Type 'string | null' is not assignable to type 'string'.

Perhaps the impact of this change would be minimal.

// L273
if (typescriptVersion.value !== 'latest' || files._tsVersion) {
  files._tsVersion = typescriptVersion.value
}

Forgot to run the typecheck command to check. Thank you for your suggestion. I have already modified it.❤️
