feat: Enhance Jina client with additional embedding parameters

- Add `type_`, `truncate`, and `late_chunking` parameters to the
  `create_embeddings` function for finer control over embedding
  generation. This allows users to specify embedding type,
  truncation method, and whether to apply late chunking.
- Rename model parameter to `model` for clarity and consistency.
- Improve model enum naming for better readability and API consistency.
- Add unit tests for the `create_embeddings` function to ensure
  correct functionality and handle potential errors.
