Improve documentation on Synchronisation

[keunes]

Short description: Describe that synchronisation must happen via a central point, a server. That these servers can be offered by big parties shared by many users (risk: slow if not funded). Or that you can self-host a server (downside: more effort). Describe that 'address of webserver' is the URL of the server on which you have an account.

Location: https://antennapod.org/documentation/general/synchronization

Why have this:

Works well enough, but synchronizing between devices with gpodder is completely broken, and documentation is non-existent. When I try to set it up, it gives me a blank text box and wants me to enter "Host name". What does that even mean?? No documentation.
