Enable TLS verification for `vault-config-operator` 's CRDs

Currently, when CRDs of the vault-config-operator (API redhatcop.redhat.io/v1alpha1) connect to vault, the TLS verification is skipped because of a bug of the operator.

When a fix is available, update the vault-config-operator and configure the .spec.connection section accordingly:

    tLSConfig:
      tlsSecret:
        name: vault-tls
