Move this repo to devonfw-training

[hohwille]

Actually this repository is located in the wrong github organisation. Instead of devonfw it should be located in devonfw-training:
https://github.com/devonfw-training/

I will move this repo to the corrent devonfw-training organisation. However, with this issue I am informing the makers of this repo. If there is any concern, please immediatly speak up by directly contacting me or commenting this issue. Otherwise I will proceed and move the repo soon.
