Error: Failed to resolve directive: interpolation

Hi there,
Thanks a lot for your Nuxt3 package - it's perfect for displaying links from third-party content :bow:
I had a bit of trouble setting the module up as I followed the instructions on the README.md and then when trying to run the project I would get an error along the lines of:
```
[Vue warn]: Failed to resolve directive: interpolation
[nitro] [unhandledRejection] TypeError: Cannot read properties of undefined (reading 'getSSRProps')
at Module.ssrGetDirectiveProps (.../node_modules/@vue/server-renderer/dist/server-renderer.cjs.js:489:40)
at _sfc_ssrRender (.../index.vue:161:165)

at process.processTicksAndRejections (node:internal/process/task_queues:95:5)

```
However, adding `nuxt3-interpolation` to the `modules: []` section of my `nuxt.config.ts` fixed this.
I'm sure it's obvious that this is needed, but as I had never seen a `buildModules` directive before I assumed this was all that was needed.

Anyway, there's not actually an issue. But I think the README.md should be updated to include mention of adding the package name to the `modules` section. I've left the title as-as to help anyone else having the same issue find this thread easily.

Thanks again.
