Set minimum Kubernetes version in operator CSV

[adambkaplan]

Feature request

Set the minimum Kubernetes version supported by the operator. API deprecations and additions may alter which version of Kubernetes the operator can deploy on.

Use case

• Deploying the operator on Kubernetes versions that may no longer be supported by the upstream community
• Ensuring the operator is not deployed on Kubernetes clusters that are missing required APIs.

@vdemeester where can I get minimum kubernetes supported version of pipeline v0.50.x?
I do not see v0.50.x from the list here: https://github.com/tektoncd/pipeline#required-kubernetes-version

I think we have to use that version as minimum supported k8s version in operator, right?

Starting from the v0.45.x release of Tekton: Kubernetes version 1.24 or later
Starting from the v0.51.x release of Tekton: Kubernetes version 1.25 or later

'Starting from' is the key piece here, this list only shows the releases where the minimum Kubernetes version changed.

Since v0.50.x falls between these two, the minimum supported version would be 1.24
