fix(vue): remove writeGlobalTypes

**Problem** twoslash-vue fails with newer versions of `@vue/language-core (3.1.1+)` due to importing writeGlobalTypes, which is no longer exported: ``` SyntaxError: The requested module '@vue/language-core' does not provide an export named 'writeGlobalTypes' This breaks projects using twoslash-vue with newer @vue/language-core versions (e.g., Slidev). ``` This breaks projects using `twoslash-vue` with newer `@vue/language-core` versions (e.g., Slidev). **Solution** - Removed the `writeGlobalTypes` import from `@vue/language-core` - Removed the `writeGlobalTypes(vueOptions, ts.sys.writeFile)` call In `@vue/language-core 3.1.1+`, `writeGlobalTypes` was reimplemented without side effects and is handled internally by the Vue language plugin, so the explicit call is no longer needed. **Changes** - Removed unused `writeGlobalTypes` import - Removed `writeGlobalTypes()` call in `getLanguage()` - Kept `CompilerOptionsResolver` for Vue compiler options resolution **Testing** - Build passes - No linting errors - Type checks pass - Existing functionality preserved
