[KrystianMarek]

Description

Drop caBundle from CRDs to support Kubernetes 1.31
kubernetes-sigs/cluster-api#10972

Why is this needed

Allow provider to work with k8s 1.31

Fixes: #

message: 'action failed after 10 attempts: failed to patch provider object: CustomResourceDefinition.apiextensions.k8s.io
      "tinkerbellclusters.infrastructure.cluster.x-k8s.io" is invalid: spec.conversion.webhookClientConfig.caBundle:
      Invalid value: []byte{0xa}: unable to load root certificates: unable to parse
      bytes as PEM block'

Tests:

Deployed on local k8s 1.31, with tilt.

@KrystianMarek i don't recall the semantics of the API server pre 1.31. How does this impact deployments to Kube <1.31?
