[Feature] Add Debian support for aarch64.

[Conan-16]

Is your feature request related to a problem? Please describe. I'm using a M1 Mac, and when I try to launch a debian_11.3.0 image, no matter I use "--arch aarch64" or not, it fails with "unable to download debian_11.3.0-aarch64.qcow2 for aarch64: requested image download is not supported: StatusCode 404"

But when I use "--arch x86_64", it starts retrieving image and booting successfully.

Describe the solution you'd like Add Debian support for aarch64.

Describe alternatives you've considered Or tell users there is no supported Debian images for aarch64 now, if users still want to launch a Debian image, please use "--arch x86_64" manually instead.

Additional context Also, it would be great if users can know which image are supported, it also helps users to launch an image more easily. For now, I know only alpine and Debian are supported by typing a random image name.
