feat: Add helper script to aid in keeping proto files up to date

[bryantbiggs]

• Add helper script to aid in keeping proto files up to date
  • Its not perfect but it helps with the bulk of the task - there will still be additional, manual involvement to update/resolve any changes in the rust code
  • It currently is only updating protos from the containerd organization, but can be extended to the other vendored sources if this seems valuable/useful
• There are a few changes related to cgroups:
  1. Both v1 and v2 are being pulled in so they have been namespaced under their respective version. Since the existing implementation is using v1, that has been maintained through this change. In a later PR, we can look at if/how to expose v2 to users behind a feature flag
  2. I suspect I am doing something wrong or mis-understanding because where is github.com/containerd/cgroups/v3 ?! I see it used here and referenced across the contaienrd project but I don't see where that v3 is located or coming from. If I go to the cgroups repository I only see cgroup1/, cgroup2/ and cmd/ directories
• Upstream PR to fix a missing namespace that causes tonic to crash https://github.com/containerd/containerd/pull/9126

Open to thoughts/feedback - and I've loved to help document some of this once its ironed out

This took me a while to figure out too, It is coming from https://github.com/containerd/cgroups/blob/v3.0.2/go.mod#L1

I need to revisit this when I get some time - it doesn't work well across platform (Linux vs MacOS) as its written

This was solved in https://github.com/containerd/rust-extensions/pull/244, so I'm going to close this one. Let us know if there any missing bits left.
