Diagnostic code 8030 being incorrectly generated using JSDoc `@type` on a function.

Personne n'a encore pris cette issue.

### 🔎 Search Terms

Diagnostic 8030 is being generated incorrectly when using JSDoc `@type` on a method when the type is being referred to from an interface. This is using the new `tsc` LSP - version 7.0.2.

### 🕗 Version & Regression Information

- This changed between versions 7.0.0-dev.260707.2 and 7.0.2.
- This is the behavior in every version I tried, and I reviewed the FAQ for entries about new native issues being transferred into the main typescript repo.

### 💻 Code

```ts
// types.ts
interface Example {
method (): number;
}
export {};

// code.js
const exampleFns = {
/**
* @type {Example['method']} // A JSDoc `@type` tag on a function must have a signature with the correct number of arguments.
*/
method () {
return Math.random();
}
};
```

### 🙁 Actual behavior

in this example, the diagnostic and LSP info does not tell the user that typescript is internally suffixing `| undefined` to the type. As such wrapping the type in `NonNullable` removes the error diagnostic, I do not believe this to be intended behaviour as previous iterations the golang native LSP `tsgo` (7.0.0-dev.260707.2) did not produce this diagnostic, nor did previous versions of typescript.

### 🙂 Expected behavior

The type should be properly referenced with no additional suffixing of types, as it used to.

### Additional information about the issue

_No response_

Commencez par reproduire le diagnostic avec types.ts et code.js en utilisant la version de TypeScript 7.0.2 signalée ainsi que la version antérieure 7.0.0-dev.260707.2. Suivez la manière dont la référence JSDoc @type vers Example['method'] est résolue et pourquoi | undefined est ajouté. Le travail est terminé lorsque le type de méthode valide ne produit plus le diagnostic 8030 et qu’une couverture de régression existe pour cet exemple.
