Named parameters, how?

Hi,


I was following this video (https://www.youtube.com/watch?v=U6k7HnQiWzc) and tried to do the same in js.
While the nodejs [API](https://duckdb.org/docs/api/nodejs/reference) has `...params` for nearly every function, it seems like named paramaters isn't a thing on the js side?

I couldn't get it working.
For example:
```
const result = await db.run(`SELECT a, b, array_cosine_similarity(
embedding, $searchVector::FLOAT[1024]) as score FROM x ORDER BY score DESC LIMIT $limit`, {"searchVector": await embeddingContext.getEmbeddingFor("test"), "limit": 10});
console.log(result);
```

Returns:
```
[Error: Invalid Input Error: Values were not provided for the following prepared statement parameters: limit, searchVector] {
errno: -1,
code: 'DUCKDB_NODEJS_ERROR',
errorType: 'Invalid Input'
}
```

It should be on par with what python does yet it is just not working. It is not implemented for the js side of things?

Sidenote, i'm running [duckdb-async](https://github.com/motherduckdb/duckdb-async) but it wraps this library so errors there probably originate here.
