Support for native aarch64 setups

### Feature description

At least since MacBooks switched to ARM, support for aarch64 would be nice. Generally we have no intrinsic x86_64 dependency but dependencies on Debian-based OSs and Docker are so fundamental, that the first check has to be if there are issues there.
If there is no way to make this work, a completely fresh install e.g. on MacOS could still be pursued as well.
