Please describe what the rule should do:

When we use Option API (in typescript and javascript) it is better to use defineComponent to enable props type inference (1).
A rule should be available to enforce it.

What category should the rule belong to?

• Enforces code style (layout)
• Warns about a potential error (problem)
• Suggests an alternate way of doing something (suggestion)
• Other (please specify:)

Provide 2-3 code examples that this rule should warn about:

Should error on:

<script lang="ts">
export default {
 // ...
}
</script>

<script>
export default {
  // ...
}
</script>

Should not error on:

<script lang="ts">
export default defineComponent({
  // ...
})
</script>

<script setup>
// ...
</script>

<script lang="ts" setup>
// ...
</script>
