async script setup support (Top-level 'await')

When checking a component with an async script setup like:

<script setup lang="ts">
const pendingMessage = await Promise.resolve('Hello');
</script>

then Volar throws:

src/components/HelloWorld.vue:8:24 - error TS1378: Top-level 'await' expressions are only allowed when the 'module' option is set to 'esnext' or 'system', and the 'target' option is set to 'es2017' or higher.

8 const pendingMessage = await Promise.resolve('Hello');

That makes sense, and we can workaround it by updating the target to es2017 but I was wondering if that could be supported out of the box?

@rafasoares try add

  "include": [
    "**/*.ts",
    "**/*.js",
+    "**/*.vue",
  ],

@WTFace It’s only for <script setup> but not for .ts.
