Update certmanager chart to 1.5 for Kubernetes 1.22 support
What does this MR do?
This MR updates the version of certmanager we bundle from 1.2 to 1.5.
As specified in the certmanager 1.5 release notes, "If you intend to upgrade to Kubernetes 1.22, you must upgrade to cert-manager 1.5." It appears most of the deprecations related to API version changes were already addressed with #2756 (closed).
1.5.4 is the latest official release of certmanager at this time, so we'll use that version.
