How to use RPCs correctly unclear for new users

[LukeStampfli]

Feedback
There are a few ways to wrongly define an RPC. If a user wrongly defines an RPC they get no error message at compile or runtime and instead the RPC is executed like a regular C# function.

• Making a static function into an RPC.
• Defining an RPC on a MonoBehaviour instead of NetworkBehaviour.

I encountered this issue very frequently when helping users on Discord.

Suggested Changes
We can try to solve this with better documentation but I doubt that will help much.

We should have clear feedback when writing MLAPI code when a user is defining a wrong RPC. Roslyn Analysers might be able to provide that.

We do have a compile error on statics, missing suffix, etc. No errors for using the attributes on a class type other than NetworkBehaviour... should consider this.

Closing this issue as it will be handled in documentation.
