Add GH-repository link to Synapse Playground demo

[rjan90]

Problem

Users visiting https://demo.filecoin.cloud/ have difficulty finding the source code. It would be helpful to have a direct link to the GitHub repository.

Proposed Solution

Add a "View Source" or "GitHub" link to the demo site that directs users to: https://github.com/FilOzone/synapse-sdk.

Isn't the github icon linked already added to the Navbar in top with redirection to the url (https://github.com/FilOzone/synapse-sdk).
