doc: Use self-closing tags for `return` and `argument`

For the time being we don't support writing a description for those, preferring
having all details in the method's description.

Using self-closing tags saves half the lines, and prevents contributors from
thinking that they should write the argument or return documentation there.

 			<description>
 				Sets the compression method used for network packets. These have different tradeoffs of compression speed versus bandwidth, you may need to test which one works best for your use case if you use compression at all.
 				[b]Note:[/b] Most games' network design involve sending many small packets frequently (smaller than 4 KB each). If in doubt, it is recommended to keep the default compression algorithm as it works best on these small packets.

 				Create client that connects to a server at [code]address[/code] using specified [code]port[/code]. The given address needs to be either a fully qualified domain name (e.g. [code]"www.example.com"[/code]) or an IP address in IPv4 or IPv6 format (e.g. [code]"192.168.1.1"[/code]). The [code]port[/code] is the port the server is listening on. The [code]channel_count[/code] parameter can be used to specify the number of ENet channels allocated for the connection. The [code]in_bandwidth[/code] and [code]out_bandwidth[/code] parameters can be used to limit the incoming and outgoing bandwidth to the given number of bytes per second. The default of 0 means unlimited bandwidth. Note that ENet will strategically drop packets on specific sides of a connection between peers to ensure the peer's bandwidth is not overwhelmed. The bandwidth parameters also determine the window size of a connection which limits the amount of reliable packets that may be in transit at any given time. Returns [constant OK] if a client was created, [constant ERR_ALREADY_IN_USE] if this ENetMultiplayerPeer instance already has an open connection (in which case you need to call [method close_connection] first) or [constant ERR_CANT_CREATE] if the client could not be created. If [code]local_port[/code] is specified, the client will also listen to the given port; this is useful for some NAT traversal techniques.

 			<description>
 				Initialize this [MultiplayerPeer] in mesh mode. The provided [code]unique_id[/code] will be used as the local peer network unique ID once assigned as the [member MultiplayerAPI.network_peer]. In the mesh configuration you will need to set up each new peer manually using [ENetConnection] before calling [method add_mesh_peer]. While this technique is more advanced, it allows for better control over the connection process (e.g. when dealing with NAT punch-through) and for better distribution of the network load (which would otherwise be more taxing on the server).

 				Create server that listens to connections via [code]port[/code]. The port needs to be an available, unused port between 0 and 65535. Note that ports below 1024 are privileged and may require elevated permissions depending on the platform. To change the interface the server listens on, use [method set_bind_ip]. The default IP is the wildcard [code]"*"[/code], which listens on all available interfaces. [code]max_clients[/code] is the maximum number of clients that are allowed at once, any number up to 4095 may be used, although the achievable number of simultaneous clients may be far lower and depends on the application. For additional details on the bandwidth parameters, see [method create_client]. Returns [constant OK] if a server was created, [constant ERR_ALREADY_IN_USE] if this ENetMultiplayerPeer instance already has an open connection (in which case you need to call [method close_connection] first) or [constant ERR_CANT_CREATE] if the server could not be created.

 				Sets the timeout parameters for a peer. The timeout parameters control how and when a peer will timeout from a failure to acknowledge reliable traffic. Timeout values are expressed in milliseconds.
 				The [code]timeout_limit[/code] is a factor that, multiplied by a value based on the average round trip time, will determine the timeout limit for a reliable packet. When that limit is reached, the timeout will be doubled, and the peer will be disconnected if that limit has reached [code]timeout_min[/code]. The [code]timeout_max[/code] parameter, on the other hand, defines a fixed timeout for which any packet must be acknowledged or the peer will be dropped.

 				Configures throttle parameter for a peer.
 				Unreliable packets are dropped by ENet in response to the varying conditions of the Internet connection to the peer. The throttle represents a probability that an unreliable packet should not be dropped and thus sent by ENet to the peer. By measuring fluctuations in round trip times of reliable packets over the specified [code]interval[/code], ENet will either increase the probably by the amount specified in the [code]acceleration[/code] parameter, or decrease it by the amount specified in the [code]deceleration[/code] parameter (both are ratios to [constant PACKET_THROTTLE_SCALE]).
