Support Nuxt v3.0.0 (stable)

**Describe the bug**
When I'm trying to use this module with the (just released) stable 3.0.0 version I get the following error:

```
Error while requiring module nuxt-jsonld: SyntaxError: The requested module '@nuxt/kit' does not provide an export named 'addAutoImport'
```

**Your Nuxt version**

**Your nuxt-jsonld version**
