Tristan Cacqueray 8c6ad5f431 Update CRD apiVersion to v1 (from v1beta)
This change enables installing the zuul-operator on a recent cluster,
where CRD are no longer beta:

- Update apiVersion in the CRD
- Update cert-manager to v1.8.2
- Update pxc to v1.10.0
- Add openAPIV3Schema to zuul crd (from https://review.opendev.org/c/zuul/zuul-operator/+/800302)
