Update to New Operator API Version

[TimPansino]

• Updates all languages to use v1beta1 API Version for the new operator changes.
• Updates chart value setters to use controllerManager.manager.image.version instead of controllerManager.manager.image.tag
• Add check to ensure test pods have initcontainer injected before running E2E tests.
• Refactor Makefile scripting to be more clean.

Will this fix https://github.com/newrelic/newrelic-agent-init-container/actions/runs/12938075032/job/36087424632 and allow our latest (12.11.2) image to be published?

Cool. We have a patch release of Node.js that needs to go out to solve a customer issue and they are blocked on installing it because they rely on these images.

Thanks for chasing this down!

@TimPansino, thanks for putting this together! I have a few comments/questions about the changes.

Also, I'm not really familiar with Makefiles, so I apologize if some of these comments are really basic.

This was my first time running the Makefile on my machine. The script wouldn't complete if I just ran the all command. When I followed the steps in the README to run each step individually, it worked. After that point, if I ran all, it would work.

That might be a problem that predates this PR, but wanted to call it out JIC.

Other people have had that problem too, I think it's just a timing thing. The minikube cluster or the operator might need more time to settle. Might adjust that later.

I like the Makefile, that is a convention that is popular in the Kubernetes ecosystem and I am sure customers will like it. Since the Go team does not have an agent operator integration yet, don't let my comments hold you guys back.

I spent a lot of professional time managing resources in Kubernetes environments, so if you wanted an extra set of eyes I'm happy to help out from time to time.
