Instead of pinning a specific 6.0.x redis version we just set 6.0 bra…

…nch instead so that it will automatically build the latest 6.0 tag for the user. In the Makefile we choose the version anyway what we want to build. This also fixes the slight annoyance that all images has to be rebuilt when we just want to bump the latest version and nothing else. Also updated github URL to point to redis/redis as the repo has been moved there.
