The issue #156 says to create a follow-up ticket for how to solve this in V2 in service-provider-crossplane. Is that just supposed to be a reminder ticket or how detailed should that be?

Thanks @AndresNico for this PR. I'll review it asap.

Since service-provider-crossplane is working the same way as in the control-plane-operator (via the juggler package), I'd expect the implementation would look quite similar. For now, simply create a placeholder issue in the service-provider-crossplane repo mentioning the issue and this PR and then I will take a look and fill it with more life 🚀

I'll have a look into the failing GH Actions beginning next week 👀

@maximiliantech looks like setup-envtest is causing these problems. Apparently they switched away from using GCS bucket but setup-envtests in version release-0.16 still defaults to that location. (kubernetes-sigs/controller-runtime#2811)
Do we want to just overwrite the version in Taskfile.yaml or do we want to update the build submodule? That currently uses release-0.23
