ref-manual: update tested and supported distros

According to currently active workers
https://autobuilder.yoctoproject.org/typhoon/#/workers
and to the "workers_prev_releases" definition
in https://git.yoctoproject.org/yocto-autobuilder2/tree/config.py

Also correct the text saying that SANITY_TESTED_DISTROS
lists currently tested distros.

Also replace AlmaLinux 8.8 and 9.2 by just AlmaLinux 8 and 9,
as we update our workers anyway.
