commit 10c7f03b3b updated google.golang.org/protobuf
to v1.33.0, which addresses CVE-2024-24786, however a follow-up post on the
Golang security list issued a warning that the v1.33.0 update introduced a
breaking change, causing compatibility with github.com/golang/protobuf to be
broken;
> A small correction: This vulnerability applies when the UnmarshalOptions.DiscardUnknown
> option is set (as well as when unmarshaling into any message which contains a
> google.protobuf.Any). There is no UnmarshalUnknown option.

Containerd itself does not appear to be using this code, but consumers may be,
so update the github.com/golang/protobuf to restore compatibility.
