Update to containerd 2.0

[dmcgowan]

This is testing against beta, opening now to see if there are any glaring issues we should consider before 2.0 final. We plan on stabilizing the Go interface in 2.0 so future versions shouldn't require many code changes that are included here.

Requires #4558 https://github.com/containerd/stargz-snapshotter/pull/1545 https://github.com/containerd/fuse-overlayfs-snapshotter/pull/72
