I run the workflow manually after merging #5868

There are two interesting notes here:
1- The PR got recreated even if I didn't check the rebase/retry checkbox, which is useful
2- Again, the CI didn't run, so it's something we need to look into.

[juanluisvaladas]

Looks like it doesn't run go mod tidy, which is odd.

[juanluisvaladas]

needs go mod tidy

Alright, the PR looks good. However, we need to test it carefully because it's the first feature release in several years. Also, @jnummelin said he heard about some dragons hiding in the dark wrinkles of the upgrade path.

Also there is a breaking change in an API we use.

I'll close and reopen to force the CI to run to verify that the go mod tidy work actually worked entirely as we expected even though I checked it locally on my machine.

[juanluisvaladas]

As for the upgrade I did a quick reading on etcd documentation and I verified we aren't using any of the deprecated/removed flags. I believe all we need to do is:

1- Before starting etcd check if the cluster is healthy and the etcd version of the peers
2- If the leader is running v3.5, make a snapshot of the leader just in case
3- Start etcd and verify that everything is healthy

So assuming it's just what the docs say, it looks like most of the effort will be testing and documentation.

Trying to do the same as for the old kine PR. Closing/renaming this, and deleting the branch, so that it gets recreated with the right user.
