Fix autocomplete for Databases.createDocument

Fixes #76

Update `createDocument` method to improve TypeScript autocompletion.

* **src/models.ts**
  - Remove the string index signature from `Models.Document`.
  - Add a new type `AnyDocument` extending `Models.Document` with the string index signature.

* **src/services/databases.ts**
  - Update `createDocument` method to use `T extends Models.Document = Models.AnyDocument`.
  - Update `data` parameter type to `Omit<T, keyof Models.Document>`.
