Subject: [PATCH] link to playground in embedded playgrounds

Summary:
The "copy share URL" button only works in the standalone playground, not the ones embedded on the landing page or the documentation, because, we don't want people to share a link to a modified documentation page.

This diff replaces the share URL button with a link to a standalone playground which then can be shared.
