Installs follow registry.quineglobal.com/quine-linux

The live ISO's installs now pull and update from
registry.quineglobal.com/quine-linux:latest (Taskfile's UPDATE_IMAGE),
our own pull-only name for the forge's image, instead of the forge's
hostname, so the update source outlives where the images are stored. CI
still pushes to the forge.

 install ISO.
