copper backport

Some players are using Minecraft 1.20.6 servers but still want to build with copper grates and copper bulbs. However, enabling Experimental Features also activates Trial Chambers and changes raid mechanics. What can they do? This mod adds copper grates and copper bulbs without requiring Experimental Features. Only the server or the host needs to install this mod! 有的人服务器版本是1.20.6，但很想用铜格栅铜建造东西，开了实验性玩法后又会生成试炼室和改变袭击规则。怎么办呢？！本mod可以在不开启实验性玩法下添加了铜格栅和铜灯，而且仅需要服务器端或房主安装本mod!
