Update example app with new demo server

[d4rken]

The previous one was lost? when it went Piwik -> Matomo.

The new one is demo2.matomo.org, ID 81.

@hannesa2 You should have gotten an invite with admin access to the server. Might have been flagged as spam?

I followed all required steps and ended here

To be honest, I don't know what's the purpose of it

The PR to get the demo app working correctly, and the invite f you want to test something, you don't need to pay/host an instance yourself.
