Send the version required by the server to the client

[LittleChest]

When the versions required by the client and the server are inconsistent, the version required by the server is sent to the client, so that on the client's server list page, you can see the server's delay icon showing "Incompatible version!"

[Andre601]

The plugin already sets the required protocol version by using the first entry in the protocol version list.
