5210R: ISO image updated (AlmaLinux 8.8)

AlmaLinux 8.8 has just been released and we updated our BlueOnyx 5210R image accordingly.

With the new release of the AlmaLinux 8.8 ISO image we also revised our ISO building procedure a little and published a new installation image for BlueOnyx 5210R based on the AlmaLinux 8.8 ISO image.

If you already have a BlueOnyx 5210R running, a YUM update will get you fully current and the latest set of updates seem to be entirely unproblematic.
