This commit updates to images v0.117.0 so that the cross-distro.sh
test works again (images removed fedora-39.json in main but the
uses the previous version of images that includes fedora-39 so
there is a mismatch (we should look into if there is a way to
get github.com/osbuild/images@latest instead of main in the
cross-arch test).
It also updates all the vendor stuff that got pulled via the
new images release (which is giantonormous).
This update requires updating the Go version to 1.22.8
Update the images dependency to v0.18.0
This includes a change in the Fedora IoT remote configuration which is
now installed through an RPM instead of being hard-coded in the image
definitions.
