Link to cloud images on www.d.o/distrib

[Thomas Lange <lange@cs.uni-koeln.de>]

Hi,

on the web page www.debian.org/distrib I've replaces the links like
  https://cloud.debian.org/images/cloud/bookworm/latest/debian-12-generic-amd64.qcow2
with
  <cloud-current-url/>-generic-amd64.qcow2
and similar types of images (raw, nocloud, arm64,...)

<cloud-current-url/> is now defined in the webwml repository in
english/template/debian/release_images.wml as follows:
<define-tag cloud-current-url>https://cloud.debian.org/images/cloud/bookworm/latest/debian-12</define-tag>
                                                                    ^^^^^^^^               ^^

When a new release of the cloud images is available we only have to
update this variable. Then all translations will point to the new images.
