Please add aliases for latest images

[emilfihlman]

Instead of having to add glue myself to find the latest version, please add aliases to latest versions of images that update automatically

For example

debian
debian/stable
debian/latest/stable
etc

would currently be aliases for debian/12, and when 13 comes around, change to that.

Debian links to these in https://www.debian.org/releases/

Another scheme is also fine, but it would be best if there wouldn't be a need to manually select version numbers

There is already precedent to this with the current, next etc names for gentoo/funtoo and kali.

Ie debian/stable, debian/unstable and debian/testing should at least exist as aliases
