ci: nerdctl: Create the containerd config

Otherwise we'll fail to configure kata-containers in the `install-kata`
step.

This is mostly needed because the nerdctl-full tarball doesn't provide a
contaienrd configuration, just the binary, as contaienrd does not
actually require a configuration file to run with the default config.
