chore: fix the output of `etcdctl watch -i`

[JalinWang]

Please read https://github.com/etcd-io/etcd/blob/main/CONTRIBUTING.md#contribution-flow. Although the interactive mode of etcdctl watch supports progress command now, the output is a little bit out-of-date :(

Hi @JalinWang. Thanks for your PR.

I'm waiting for a etcd-io member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.
