Add Tailscale as an alternative option to ngrok for remote connectivity to Pieces OS

In a recent conversation on Discord, a user asked a question whether the user can use Tailscale instead of ngrok for the remote URL setup while using Pieces OS.

I have tested Tailscale and it works completely fine. So we can add it's reference in the documentation. We don't need to necessarily add complete walkthrough steps. But just a reference: that you can use Tailscale as well would be great.
