我更新了UE5版本，怎么发pull request？ #3
Description
为了在一个UE5项目中使用，我在一些跨版本编译的部分增加了ENGINE_MAJOR_VERSION的判断，修复了UE5引擎更新引发的几个问题，如一些类的变量类型由FVector改为FVector3f，以及SSCSEditor被弃用，改用SubobjectEditor的问题。虽然工作量不是很大，但是我想知道我如何提交这些更改的代码？
In order to use this plugin in a UE5 project. I added some ENGINE_MAJOR_VERSION macro branch to support across versions compiling and fixed some problems caused by the Engine update. For example, the type of some fields was changed from FVector to FVector3f and SSCSEditor was deprecated. Although the work is not very hard, I would like to know how can I submit my changes?
