The normal youtube video and the shorts have same embed code format.
It would be good if it has youtube shorts url regex in default Media Embed provider within youtube.

How the feature works now and what you'd like to change?

I was trying to add extraProvider for youtube shorts, but keep failing on save and display the content.
If the youtube shorts url is in regex with youtube, it will solve without adding extraProvider.
Not sure this is the correct place to add or not, but here is where I found the default regex for youtube.
