Bring back embedded demos on component docs

[aliabd]

Brings back the embedded component demos on the docs, now with lite and mdsvex.

A few had issues with lite, will figure them out separately: DownloadButton, FileExplorer, LoginButton, LogoutButton, SimpleImage. Potentially I could make just those embedded spaces.
