Better user journey for remote hosting

[Sytten]

New users need to understand a few concepts to be able to host caido remote:

1. What are the options: cli, docker, etc
2. How to secure access
3. ...

Right now I dont have a good guide/tutorial/concept I can point them to and expect they will understand.

We have https://docs.caido.io/app/guides/vps.html (doesnt explain the CLI, https://docs.caido.io/app/guides/docker.html (which very outdated) and https://docs.caido.io/app/tutorials/instance_internet.html (which is closer but still not perfect)

We also need to explain the limits, its not true multiplayer, etc.
We should link to Drop as an alternative
