Changelog Entry

Description

Fixes a series of cascading errors in the YouTube transcript retrieval functionality. The initial "no element found" error reported was a red herring for a chain of unhandled exceptions in the backend, including ParseError, AttributeError, and TypeError when fetching transcripts from certain videos. This change makes the YouTube video embed feature more robust by preventing backend crashes when a transcript is unavailable or invalid.

Fixed

YouTube Transcript Fetching:
- Resolved a TypeError when raising the NoTranscriptFound exception by providing the required video_id, requested_language_codes, and transcript_data arguments.
- Prevented an xml.etree.ElementTree.ParseError by wrapping the transcript.fetch() call in a try...except block to gracefully handle empty or invalid XML responses from the youtube_transcript_api.
- Fixed an AttributeError by correctly accessing the .text attribute on FetchedTranscriptSnippet objects instead of attempting to use the .get() method.
