Invalid dates in two blog articles

[sftim]

This is a Bug Report

Split out from issue #48752

Problem:

• content/en/blog/_posts/2018-01-00-Reporting-Errors-Using-Kubernetes-Events.md has an invalid published date in front matter
• content/zh-cn/blog/_posts/2019-12-09-kubernetes-1.17-release-announcement.md has an invalid date in its front matter

This shows up with newer releases of Hugo.

Proposed Solution: Edit those pages to use valid ISO8601 dates.

Page to Update: https://k8s.io/blog/2018/01/reporting-errors-using-kubernetes-events/ https://kubernetes.io/zh-cn/blog/2019/12/09/kubernetes-1-17-release-announcement/
