TypeScript: Could not find a declaration file for module 'vue-mention'

Hi!

Thank you very much for this impressive project.

I get the following error when running `vue-tsc --build`:

```text
error TS7016: Could not find a declaration file for module 'vue-mention'. '.../node_modules/vue-mention/dist/vue-mention.es.js' implicitly has an 'any' type.
There are types at '.../node_modules/vue-mention/dist/index.d.ts', but this result could not be resolved when respecting package.json "exports". The 'vue-mention' library may need to update its package.json or typings.
```

Let me know if I can help.

Best regards,
Benoit
