Expand supported media types for embed

It would be great if there was ongoing enhancement to the supported media types for embedding into Community articles, product updates, etc. Based on this article, it doesn’t appear that there have been many additions in the last few years, and I’m sure new sites created regularly that need to be reviewed and added to the supported list.

Today, I’m looking for the ability to embed a demo from tourial.com and a document from highspot.com
