fix: support containerd v2 sandbox config and ignore pause image pull…

[jiazhiguang]

… errors

Containerd v2 renamed sandbox_image to sandbox in its config. The sed command now replaces both keys so the pause image is set correctly regardless of the containerd version. Also adds ignorePreflightErrors: [ImagePull] to init/join nodeRegistration so kubeadm does not fail when the built-in pause tag differs from the registry.

Poem

🐰 With whiskers twitching at each config line,
I hop through docs to make containerd shine,
Sandboxes nested, preflight errors blessed,
Clear instructions help clusters pass the test! ✨
