🗑️ chore: Remove YouTube API integration (#11331)

* 🗑️ refactor: Remove YouTube API integration and related configurations as it's broken and should be integrated via MCP instead. Currently there seems not to be a single MCP out there with working get_transcript methods for months. API seems to have changed and there are no maintainers on these projects. We will work out something soon an MCP solution

- Deleted YouTube API key and related configurations from .env.example.
- Removed YouTube tools and their references from the API client, including the manifest and structured files.
- Updated package.json to remove YouTube-related dependencies.
- Cleaned up toolkit exports by removing YouTube toolkit references.

* chore: revert package removal to properly remove packages

* 🗑️ refactor: Remove YouTube API and related dependencies due to integration issues
