[stable34] build(deps-dev): Bump vue-tsc from 3.2.8 to 3.3.0

[dependabot]

Bumps vue-tsc from 3.2.8 to 3.3.0.

Release notes

Sourced from vue-tsc's releases.

v3.3.0

Features

Refined Autocomplete for Component Props

Previously, we inferred props used for autocomplete from the component itself's type, which did not work well with components whose props need to be inferred dynamically, such as generics or discriminated unions.

Now, we have improved this feature to better align with TS behavior. See the following example:

<script lang="ts" setup>
  defineProps<
    | { type: "foo"; foo: string }
    | { type: "bar"; bar: string }
  >();
</script>
&lt;template>
<Self type="foo" :| />
<!--              ^ [foo, ...] -->
<Self type="bar" :| />
<!--              ^ [bar, ...] -->
</template>

When triggering completions at the two positions above, we will now get the props that are actually available in each corresponding case.

(PR: #5709)

Check Required Fallthrough Attributes

Consider the following structure:

<!-- basic.vue -->
<script lang="ts" setup>
  defineProps<{
    foo: string;
    bar: string;
  }>();
</script>

<!-- comp.vue -->
<script lang="ts" setup>
  import Basic from "./basic.vue";
</script>
&lt;template>
</tr></table>

... (truncated)
