Upgrade client-go 1.28, codegen and CRD

Description

Upgrade client-go 1.28, codegen and CRD

Motivation and Context

Maintenance task to update to the latest versions of the Kubernetes SDKs/tools and APIs.

Also adds a standard "conditions-based" status object to the FunctionIngress to be populated later.

How Has This Been Tested?

Building the code locally and within Docker.

Then, ran out of cluster, after applying the CRD:

The Ingress record was created for the sample object ./examples/nodeinfo-ingress.yaml, plus a warning that may need later work:
