feat: Add include_line_confidence parameter to whisper method

[Deepak-Kesavan]

What

Added include_line_confidence parameter to the LLMWhispererClientV2.whisper() method to support line confidence scores in the line metadata.

Why

The LLMWhisperer API now supports a new include_line_confidence parameter that adds confidence scores to line metadata returned by the highlights API. This parameter needs to be added to the Python client to expose this functionality to users.

How

1. Added include_line_confidence: bool = False parameter to the whisper() method signature
2. Added the parameter to the params dictionary that gets passed to the API
3. Updated the docstring to document the new parameter and its requirements
4. Bumped version from 2.4.2 to 2.5.0 (minor version bump for new feature)

Relevant Docs

• The parameter adds line confidence to line metadata returned by the highlights API
• Requires add_line_nos to be enabled for this feature to work properly

Related Issues or PRs

• Enables support for the new include_line_confidence API parameter

Dependencies Versions / Env Variables

• No new dependencies added
• No environment variables changed

Notes on Testing

• The parameter is optional with a default value of False, maintaining backward compatibility
• When enabled, it passes through to the API which will include confidence data in line metadata
• Requires testing with the highlights API endpoint to verify confidence data is returned correctly
