knative-v1.1.0 cli is too recent for Openshift RH serverless.

Describe the bug
knative-v1.1.0 (kn cli) is too recent for Openshift RH serverless.
This tutorial should use knative-v1.0.1 instead.

To Reproduce
Steps to reproduce the behavior:
When using --scale-min option in:
kn service create prime-generator
--concurrency-target=10
--scale-min=2
--image=quay.io/rhdevelopers/prime-generator:v27-quarkus

With kn 1.1.0, it will add annotation autoscaling.knative.dev/min-scale but latest Openshift Serverless is working only with autoscaling.knative.dev/minScale

Expected behavior
minScale should be taken into account by Openshift
