Subject: [PATCH] Fix return type of AsyncDuckDBConnection.prepare

This looks like it is supposed to return `AsyncPreparedStatement<T>` but
since the type parameter is not provided it actually returns
`AsyncPreparedStatement<any>`, which passes type checking anyway since
`any` is compatible with `T`.
