rke2-images-cilium.linux-amd64.* missing and Airgap Tarball is failing

[eifelmicha]

Environmental Info:
RKE2 Version: v1.28.4+rke2r1

Node(s) CPU architecture, OS, and Version: Linux k8s-master-1 6.1.0-15-arm64 #1 SMP Debian 6.1.66-1 (2023-12-09) aarch64 GNU/Linux

Cluster Configuration: 3 Server with Cilium CNI

Describe the bug:
I would like to prefetch files in Packer to do an Tarball Installation of RKE2 and reduce startup times. According to: https://docs.rke2.io/install/airgap#tarball-method i have to download rke2-images-core and rke2-images-cilium , because of --cni=cilium
However rke2-images-cilium.linux-amd64.tar.zst does exist, while rke2-images-cilium.linux-arm64.tar.zst does not.

Steps To Reproduce:

• Scripted Curl to download files, the + is escaped before:

ARCH=amd64
if [ "$(uname -m)" = "aarch64" ]; then ARCH=arm64; fi
curl -OLs https://github.com/rancher/rke2/releases/download/$RKE2_VERSION/rke2-images-core.linux-$ARCH.tar.zst
curl -OLs https://github.com/rancher/rke2/releases/download/$RKE2_VERSION/rke2-images-cilium.linux-$ARCH.tar.zst
curl -OLs https://github.com/rancher/rke2/releases/download/$RKE2_VERSION/sha256sum-$ARCH.txt

Expected behavior:
Successful download

Actual behavior:
CHECKSUM_CILIUM_EXPECTED=$(grep "rke2-images-cilium.linux-$ARCH.tar.zst" "sha256sum-$ARCH.txt" | awk '{print $1}'); failed, because no file and checksum is present.

I believe that up until recently, some or all of the cilium images did not support arm64, so we disabled packaging it for that architecture.

rke2/scripts/build-images

Lines 36 to 37 in c1494f5

	if [ "${GOARCH}" != "s390x" ] && [ "${GOARCH}" != "arm64" ]; then
	xargs -n1 -t docker image pull --quiet << EOF > build/images-cilium.txt

@manuelbuil @thomasferrandiz can we revisit this, and see if we can package cilium airgap images for arm64?

I removed the cilium-etcd-operator since it still has no arm64 builds, but that makes sense since it was marked as deprecated in 2020 and the github repo was finally archived last year...

Thanks Mike! You should change the status of the issue to working and set the milestone to the next release :)
