Sync sample CRs from main repo during releases

[joelsmith]

We're currently missing an example for the new cloudeventsource CRD. Hopefully this change will keep that from happening in the future. As long as kedacore/keda#5921 merges before the 2.15 release, this will clean things up for that release.

So we:

• overwrite our operator kustomization yaml with the operand's
• then for each thing in it, we grab the matching sample into our repo
• then we add our kedacontroller type back to our kustomization yaml (because we overwrote ours, and the operand doesn't have kedacontroller, but we do)

Awesome. Love it.
