(0 , _highlightjsVue.default) is not a function

I think last lines should probably be changed to something like,

```javascript
var hljsRegisterVue = function(hljs) {
hljs.registerLanguage("vue", hljsDefineVue);
};

module.exports = hljsRegisterVue;
module.exports.hljsRegisterVue = hljsRegisterVue;
module.exports.hljsDefineVue = hljsDefineVue;

/**
* @deprecated
*/
module.exports.definer = hljsDefineVue;
```

Start by locating the module's final export code and reproduce the reported “_highlightjsVue.default is not a function” error. Compare the current exports with the proposed CommonJS exports in the issue; done means the module can be imported and used without that error while preserving the deprecated definer export.
