We, containerd, suggest user to use binary plugins or RPC-based plugins.
Since go plugin has too many restrictions, I'm not sure that how many users
use the go plugin to extend the core function in the production.
Based on the fact that we put a lot of effort to make external plugins
better, suggest to deprecate go-plugin type plugin in v2.0 and remove it
in v2.1

The `cri-containerd-*.tar.gz` release bundles have been deprecated
since containerd v1.6.
These bundles are no longer created in the CI, however, the
corresponding Makefile targets are still kept, as they are still used by
external CIs.

Since a recent contributor edited the synced version of this in the website (containerd.io) repo, we should just update the main repo and let the auto-sync PR get these 2 files back in sync with the latest releases.

Schema 1 has been substantially deprecated since circa. 2017 in favor of Schema 2 introduced in Docker 1.10 (Feb 2016)
and its successor OCI Image Spec v1, but we have not officially deprecated Schema 1.
One of the reasons was that Quay did not support Schema 2 so far, but it is reported that Quay has been
supporting Schema 2 since Feb 2020 (moby/buildkit issue 409).
This PR deprecates pulling Schema 1 images but the feature will not be removed before containerd 2.0.
Pushing Schema 1 images was never implemented in containerd (and its consumers such as BuildKit).
Docker/Moby already disabled pushing Schema 1 images in Docker 20.10 (moby/moby PR 41295),
but Docker/Moby has not yet disabled pulling Schema 1 as containerd has not yet deprecated Schema 1.
(See the comments in moby/moby PR 42300.)
Docker/Moby is expected to disable pulling Schema 1 images in future after this deprecation.
