LGTM, thank you

[domhanak]

Please hold the merge I will link a successful run after this update, before merging to ensure this works.

@jstastny-cz redone using make to match it with ghactions workflow.

Note that I have commits that edit helper.checkoutRepo() to work on test folder in apache jenkins, will remove once I see a green run. Currently the tests are experiencing timeouts.

@domhanak can you regen your files? Looks like you're still working on this PR. Is it worth changing to draft instead so we can review once it's done?

[domhanak]

Sure, I am investigating the issues on CI, this does not work there properly there, and the reason is yet unknown

[domhanak]

Green run:
https://ci-builds.apache.org/job/KIE/job/test/job/dhanak/job/kogito-serverless-operator.e2e.minikube-test/46/

Please take a look, keep in mind we are migrating to BDD tests in the meantime so only thing that really matters here is for this to be stable until we switch.
