not at the moment apparently, you have to wait for the next update(s). for what it's worth, i advise you to use the english editor anyhow. it makes it easier to ask for help as you don't have to translate stuff, also if you make maps for the "international" community, stuff like hotkeys are different and you can accidentally create double hotkeys is you use the german version (although this problem is probably less relevant with reforged showing hotkeys ingame at all times now)
i'm german as well and i have all modding tools (and all other games and applications for that matter) in english.
Just try it, it's not that hard to find everything you need, especially in the wc3 editor which is kinda well structured compared to others.
