We need update integration test to install brupop via helm templates once the PR be merged.

We don't necessarily need to refactor the integration tests to use helm. We will still continue to generate a single manifest that gets attached to releases, the bottlerocket-update-operator.yaml manifest. And the integration tests do a simple kubectl apply -f on that file which lands all the resources on the cluster.

But yes, a true customer end to end experience would be ideal and a stretch goal for latter releases!
