Bump prometheus-operator version to 0.88.0

In order to help address the ec2-master-scale-performance job failing in https://testgrid.k8s.io/amazon-ec2-release\#ec2-master-scale-performance,
this PR upgrades the prometheus-operator version to 0.88.0.
As a result, it will help address the job (https://prow.k8s.io/view/gs/kubernetes-ci-logs/logs/ci-kubernetes-e2e-kops-aws-scale-amazonvpc-using-cl2/2013507147345694720)
failing due to <prometheus no endpoints available for service ServiceUnavailable error> observed in the build logs.
