Update modDesc.xml

Hello Courseplay Dev team:

I'm FS15 player and we are very fond of CourseplayMoD, but without Chinese support, unfortunately, cause inconvenience to players using CourseplayMoD. So I tried this MOD from v4.0 to current v4.00.0145, translation is almost perfect. I want to ask the Chinese (CS) adds Courseplay MoD, thank you. Attached modDesc.xml file
