Removed version and channel from cert-manager

[hector-vido]

Removing version and channel from Subscription allows Openshift to select the default stable channel and version, making the onboard of new clusters easier since a fixed version can become unavailable for new releases of Openshift.

Summary by CodeRabbit

The cert-manager operator Subscription no longer pins a channel or starting version. OpenShift can select the default stable channel and version, which simplifies cluster onboarding when a fixed version is unavailable.
