upgrade guide cert-manager

We recommend that you upgrade cert-manager one minor version at a time, always choosing the latest patch version for the minor version. You should always read the release notes for the minor version to which you are upgrading. In cases where a large version jump is needed to get an installation up to date, it may be possible to do a full uninstall and re-install of cert-manager without application downtime and/or unnecessary re-issuances, however we do not guarantee that this will work for your particular setup see Reinstalling cert-manager.

とのことなので、マイナーバージョン1つずつのバージョンアップが推奨される
