Update git submodules
- Update extensions/WikimediaMessages from branch 'wmf/1.29.0-wmf.13'
- Create user group messages for wikitech.wikimedia.org
Wikitech has some specific user groups only used there. As such I've created a /wikitech/ folder to host this very specific messages. I've also tagged them as optional because translation is not really required but it won't harm if done. In addition to the en.json file, I've added a qqq.json file to host the descriptions to help possible translators.
