Ckeditor5: Different video in the docs

[scofalik]

The first thing that I did after entering docs website for this plugin was to try and play that video:

And I don't mean to _preview it_. I thought that the demo is in that video. I didn't notice that the video is already inside the editor. The video shows an editor so it is easy to think that you need to play it. I understood what's going on only after failing to "click" it a couple of times.

I'd go with a different video, something generic, like in Vimeo's case.
