[Req]: add info how to configure custom planet for Android + iPhone + iMac

[PizzaProgram]

🚀 Feature Summary

update docs for custom planet

📝 Detailed Description

It is obvious, that there is no info about it on zerotier.com, because they need to earn money.
But at ZTNet should provide some. Especially, if it's impossible, so people should be able to decide before switching to their own self-hosted planet. (Like I did.)

Case study:

I've just followed the instruction described here:
https://ztnet.network/usage/private_root#configuring-devices-with-the-new-planet-file

All went well, and I'm able to connect directly from Windows (7+11) PCs to my custom new planet controlled root, running on VPS.
But when I try that on Android, I had to realize: there is nothing I can do to set the new planet inside the app.

When I've searched the net, I've seen only 2+1 possibilities:

1. An old version, that was deciphered called ZeroTierFix (probably not legal)
2. A simple app called: magisk,
   • where you can copy your planet file if you can copy + replace it to: /data/adb/zerotier/home/planet
   • which action probably needs rooted phone
3. Same codebase, but with customised port: magisk-customPort, that is also based on the official library, claiming to fix the planet problem, by allowing to change a file and self-compile the APK. (And sign it.)

For iOS I've found this: (not tested!)

• ZeroTieriOSFix , which needs to be compiled and self-signed.

Question:

• is there some other method to use custom planet with those platforms?

You pretty much summed it up.
I'm using ZerotierFix on Android. The documentation should definitely be more clear about these platform limitations - I'll add more detailed information about the mobile constraints and available workarounds.
