/tmp doesn't exist in the kaniko executor:debug image (confirmed - no
standard FHS layout there at all), so the wget -O target failed with
"No such file or directory". Write into github.workspace instead, which
is known to exist since the build step already uses it.
Also adds the step-7 desktop-vs-k8s clarification from earlier.

actions/checkout@v4 needs a Node.js runtime, which the kaniko executor:debug
image doesn't have and has no package manager to install it with (confirmed
via a throwaway podman run - no git, no node, not even /etc/os-release).
Fetch the repo as a tarball from Forgejo's archive endpoint instead, using
wget/tar, which are actually present in the image.
