Deprecate HanaDB, HanaTranslator and update example notebook to use new implementation (#30896) 
- **Description:**  
This PR marks the `HanaDB` vector store (and related utilities) in
`langchain_community` as deprecated using the `@deprecated` annotation.
  - Set `since="0.1.0"` and `removal="1.0"`  
- Added a clear migration path and a link to the SAP-maintained
replacement in the
[`langchain_hana`](https://github.com/SAP/langchain-integration-for-sap-hana-cloud)
package.
Additionally, the example notebook has been updated to use the new
`HanaDB` class from `langchain_hana`, ensuring users follow the
recommended integration moving forward.

- **Issue:** None 

- **Dependencies:**  None
