fix(wasm-typescript): Fix option types of functions (#9662)

**Description:**

The types for the wasm-typescript functions are incorrect due to a typo.

Without this fix:

```
Property 'TransformConfig' is missing in type '{ module: true; filename: any; sourceMap:   • 
 true; mode: "transform"; transform: { verbatimModuleSyntax: boolean; nativeClassProperties:       
 boolean; importNotUsedAsValues: string; importExportAssignConfig: string; }; }' but required in   
 type 'Options'. [2345]  
```
