Documentation Link to startcloud.com

[JoelProminic]

We would like to add a link similar to #62 for https://startcloud.com/

We'll need an icon for this. @piotrzarzycki21 asked @solaechea to send some assets for this.

Once we have this part figured out, we'll need to get the document added in the domino-49 template, and it will be included in the next release.

Piotr, you should be able to see the assets here:

Let me know if you need something else.
