Markdown syntax links should not be treated as embeds

[mnaumanali94]

Summary

Today, if you have a link to a supported embed in markdown, we try to render it as an embed. Lets not do that.

Tasks

• Plain links i.e. https://www.youtube.com/watch?v=VbSPeYo8dfM should continue be rendered as embeds
• Markdown links i.e. [youtube-video](https://www.youtube.com/watch?v=VbSPeYo8dfM) should be treated as links and not as embeds
