Release/25.6.2

[raushan-skyflow]

This PR introduces enhancements to the Python SDK V2 for the deidentify_file functionality. It includes updates to both request and response formats for better consistency with other server-side SDKs (e.g., Node SDK V2). Additionally, it refines error handling to return None instead of an empty array when there are no errors.

Why:

• Included file_path in the deidentify file request for deidentification ensuring consistency.
• Added file_base64 in the response that holds the base64 of the deidentified file so users can directly access the deidentified file.
• Updated the errors field to return None when no errors are present, matching the latest behavior of the Node SDK V2 and other server-side SDKs.

Goal:

• Ensure the deidentify file request takes file_path and returns the file object.
• Maintain consistency in response structure across SDKs by setting errors to None instead of an empty list when there are no errors.

Test:

• Validated changes locally.
• Added and ran unit tests to confirm correct behavior of the new request/response structure and error handling.
