Consolidate naming for predicates unPaused vs notPaused

[enxebre]

What steps did you take and what happened:
Some times we use the term notPaused, others unPaused.

What did you expect to happen:
We should consolidate naming and terms in predicates unPaused vs notPaused and use always the same.
e.g
https://github.com/kubernetes-sigs/cluster-api/blob/main/util/predicates/cluster_predicates.go#L179-L183
https://github.com/kubernetes-sigs/cluster-api/blob/main/util/predicates/generic_predicates.go#L182

Anything else you would like to add:
[Miscellaneous information that will assist in solving the issue.]

Environment:

• Cluster-api version:
• Minikube/KIND version:
• Kubernetes version: (use kubectl version):
• OS (e.g. from /etc/os-release):

I believe they are not exactly the same. I think Unpaused may refer to update events when paused transitions to false.

ah I see, It's not clear to me why we need ClusterUpdateUnpaused rather than just checking ClusterNotPaused everywhere, I'm probably missing some context though.
