Kind image updater changes

[SgtCoDFish]

1. Fix commit description of kind-images-upgrade job
2. Remove skip-review from kind-images-upgrade PR, since the source of the kind images is a free-input release note that could contain anything. Someone should review to be sure.
3. Tighten regex rules so that we only accept things that look like version numbers and SHA256SUMs (AI-generated regexes)

I am not an expert on regexes, but the rest of the PR looks good. And AI is probably not completely off. Thanks! 🚀
