iPXE scripts in releases reference incorrect download URLs

[jbalonso]

Release https://github.com/kairos-io/kairos/releases/tag/v2.4.0 includes the iPXE script https://github.com/kairos-io/kairos/releases/download/v2.4.0/kairos-standard-opensuse-tumbleweed-amd64-generic-v2.4.0-k3sv1.27.3+k3s1.ipxe, which includes the line:

kernel https://github.com/kairos-io/kairos/releases/download/v2.4.0-k3sv1.27.3+k3s1/kairos-standard-opensuse-tumbleweed-amd64-generic-v2.4.0-k3sv1.27.3+k3s1-kernel root=live:https://github.com/kairos-io/kairos/releases/download/v2.4.0-k3sv1.27.3+k3s1/kairos-standard-opensuse-tumbleweed-amd64-generic-v2.4.0-k3sv1.27.3+k3s1.squashfs initrd=kairos-standard-opensuse-tumbleweed-amd64-generic-v2.4.0-k3sv1.27.3+k3s1-initrd rd.neednet=1 ip=dhcp rd.cos.disable netboot nodepair.enable config_url= console=tty1 console=ttyS0 rd.live.overlay.overlayfs

It's a little hard to read, but the kernel URL is https://github.com/kairos-io/kairos/releases/download/v2.4.0-k3sv1.27.3+k3s1/kairos-standard-opensuse-tumbleweed-amd64-generic-v2.4.0-k3sv1.27.3+k3s1-kernel. You will get a 404 if you try to download it. Specifically, that URL contains the substring releases/download/v2.4.0-k3sv1.27.3+k3s1/, which has a superfluous -k3sv1.27.3+k3s1.

Note, moreover, that this superfluous substring appears multiple times throughout the script. Consequently this script (and the corresponding *.ipxe-usb.img asset, probably also the *.ipxe.iso one) are unusable.

In 2.4.2 the issue is that the version is not present at all
