Use 'Add Video' for the Youtube Link + Time Stamp.

Hi, 

From my side, when I create an article, I mostly add the Youtube tutorial videos. However, if I show the specific time of the video, the ‘Add Video’ feature doesn't recognize the time stamp, resulting in the starting point. Thus, I have to go to the source code and add the time stamp, which is very inefficient if I need to handle with many articles. 

I hope the Zendesk team can improve ‘Add Video’ feature in the Guide. 

Thanks,
