fix(blocks): add YouTube Shorts URL support (#11659)

## Summary
Added support for parsing YouTube Shorts URLs (`youtube.com/shorts/...`)
in the TranscribeYoutubeVideoBlock to extract video IDs correctly.

## Changes
- Modified `_extract_video_id` method in `youtube.py` to handle Shorts
URL format
- Added test cases for YouTube Shorts URL extraction

## Related Issue
Fixes #11500

## Test Plan
- [x] Added unit tests for YouTube Shorts URL extraction
- [x] Verified existing YouTube URL formats still work
- [x] CI should pass all existing tests
