In Web Search, show video author & date

Minor UI improvement of great value

Example of video widget in Web Search

Please show AUTHOR of video. This is extremely important. Is this video from NASA? Is it from a space hobbyist? Is this a Veritasium video (ie: quality scientific content)?

Also, please show upload date. It is easier to see '12 Jan 2026' than subtract '3 months'.
The '… ago' notation is better suited for IM, chat, etc, not informational contents.
