Update hack/verify-examples-kind.sh to work better with releases

[robscott]

What would you like to be added:
Something that allows us to:

1. Run tests using the latest webhook image that has been built (latest commit, not latest release)
2. Still pass hack/verify-codegen.sh
3. Have a simple release process that allows us to at least temporarily set a fixed image version in our webhook deployment for our generated YAML attached to the release + the config/webhook YAML found at the release tag.

Why this is needed:
At one point we added the following to the script to ensure that our deployed YAML would use the latest image while our manifests on the main branch would not:

# Temporary workaround for release
sed -i 's/v0.5.0/latest/g' config/webhook/admission_webhook.yaml

This had the unfortunate affect of making a change that would cause our hack/verify-codegen.sh script to fail. #1348 (comment) resolved that issue, but it all feels like a bit of a hack. We need a more resilient solution here.

Hey @akankshakumari393 are you still interested in working on this? This is currently part of the v0.6.0 milestone, so we'd need to have this complete in the next ~2 weeks to meet our release goals.

Hey @robscott please assign it to someone else, as i may not be able give time to it.
