AC
- decide whether the doc should live at lifecycle-manager or runtime-watcher
- decide whether it is an extension to https://github.com/kyma-project/runtime-watcher/blob/main/docs/architecture.md, or if this current doc should be split into two or more parts
- e.g., one part focussing on the certificate setup, another one focusing on how to configure the watch
- use the exact terminology aligned here: [Research] have consistent watcher-related terminology lifecycle-manager#2425
- describe the overall setup including rotation applicable to both solutions
- describe where the two solutions differ (e.g. renewal of SKR certs)
