### What it does

Enforce that a `return` statement is present in `emits` validators
(in Vue.js 3.0.0+).

### Why is this bad?

An `emits` validator must return a boolean indicating whether the
emitted payload is valid. Forgetting to return a value (or returning
only falsy values) makes the validator effectively reject every emit,
breaking the component contract silently.

### Examples

Examples of **incorrect** code for this rule:

```vue
<script>
export default {
  emits: {
    foo() {
      // missing return
    },
  },
};
</script>
```

Examples of **correct** code for this rule:

```vue
<script>
export default {
  emits: {
    foo(payload) {
      return typeof payload === "string";
    },
  },
};
</script>
```
