crossplane v2 breaks on upgrades from Sylva 1.4

I have seen the following jobs failing on the same crossplane upgrade error:

The error in https://gitlab.com/sylva-projects/sylva-core/-/jobs/10979998552 and https://gitlab.com/sylva-projects/sylva-core/-/jobs/10981520775 is the crossplane Pod init container failing with:

crossplane: error: cannot initialize core: 
cannot apply crd: 
cannot patch object: 
CustomResourceDefinition.apiextensions.k8s.io "environmentconfigs.apiextensions.crossplane.io" is invalid: 
  status.storedVersions[0]: Invalid value: "v1alpha1": must appear in spec.versions

What triggers this issue is !5030 (merged).

Before working on solving the root cause (most probably an apiVersion upgrade thing) we should revert that MR.
