[Recommended] History of regular, quality releases

From CNCF TOC:

>KServe follows quarterly releases as per https://github.com/kserve/kserve/releases and https://github.com/kserve/kserve/tags.
Even though the release process from a development perspective is captured under : https://github.com/kserve/kserve/blob/master/release/RELEASE_PROCESS_v2.md, it is recommended to document at a high level the frequency/type of releases and support windows also.

Review the KServe releases and tags pages alongside release/RELEASE_PROCESS_v2.md. Document the high-level release frequency, release types, and support windows, keeping the result focused on contributor-facing guidance; done means these practices are clearly recorded without duplicating the detailed process.
