Create a periodically auto-refreshing list of fixed CVEs

With growing number of eyes on Kubernetes, the number of CVEs related to Kubernetes have increased. Although most CVEs are regularly fixed that directly or indirectly or transitively impact Kubernetes, there is no single place to programmatically subscribe or pull the data of fixed CVEs, for the end users of Kubernetes.

### Current State of the Art

All these options are broken or incomplete:

1. RSS feed with google groups is broken: https://github.com/kubernetes/website/issues/29142
2. [CVEDetails](https://www.cvedetails.com/vulnerability-list/vendor_id-15867/product_id-34016/Kubernetes-Kubernetes.html
) website seems to have incomplete data, with missing CVEs from 2021 and no mention of CVEs in base image or build time deps.
3. This page: https://kubernetes.io/docs/reference/issues-security/issues/ links to a Github issue filter for CVE related fixes but is a broad search term

### Metadata
