Recsys: add isEmbed to videos in Markdown (posts, comments) (#1765)

* Remove dead-end selector

`playingUri` resides in the `content` slice, so this returns nothing.
Nobody is using it, so should be safe to remove.

* Recsys: add `isEmbed` to videos in Markdown (posts, comments)

It seems like the existing `embedded` needs to specifically mean `/$/embed` (external from odysee.com), so had to add another variable.
