Enable running Stork on macbook M3

There are several things that need to be changed in building Stork (mainly concerning the docker Demo) to run it on macbook with M3 processor. To list the main two: the architecture name "arm64" is not recognized in the rake files. Second, we need to emulate arm64 in the docker images becuase of lack of the certain Docker images (flamethrower, bind9 image).
