Fix invalid use of markdown syntax in classref

Also:
* changed `[b]true[/b]` to `[code]true[/code]`
* use `[i]` for mathematical constant "e"
* use `[b]` for button text & menu item text
* improve markups about "tap1" and "tap2" in AudioEffectDelay

 		[Area3D] is a region of 3D space defined by one or multiple [CollisionShape3D] or [CollisionPolygon3D] child nodes. It detects when other [CollisionObject3D]s enter or exit it, and it also keeps track of which collision objects haven't exited it yet (i.e. which one are overlapping it).
 		This node can also locally alter or override physics parameters (gravity, damping) and route audio to custom audio buses.

If this is not desired, it has to be split into multiple [ConvexPolygonShape3D]s or primitive shapes like [BoxShape3D], or in some cases it may be replaceable by a [CollisionPolygon3D].

Otherwise, only the authority peer is allowed to call it and [param mode] should be kept as [code]"authority"[/code]. When configuring functions as RPCs with [method Node.rpc_config], each of these modes respectively corresponds to the [constant MultiplayerAPI.RPC_MODE_AUTHORITY] and [constant MultiplayerAPI.RPC_MODE_ANY_PEER] RPC modes. See [enum MultiplayerAPI.RPCMode]. If a peer that is not the authority tries to call a function that is only allowed for the authority, the function will not be executed. If the error can be detected locally (when the RPC configuration is consistent between the local and the remote peer), an error message will be displayed on the sender peer. Otherwise, the remote peer will detect the error and print an error there.
-				If [param sync] is set as [code]"call_remote"[/code], the function will only be executed on the remote peer, but not locally. To run this function locally too, set [param sync] to [code]"call_local"[/code]. When configuring functions as RPCs with [method Node.rpc_config], this is equivalent to setting `call_local` to `true`.
