Enable TLS verification for crds AuthEngineMount and JWTOIDCAuthEngineRole,

When enabling TLS verification for vault-config-operator's crds, the creation of crds AuthEngineMount and JWTOIDCAuthEngineRole, in the unit vault-oidc, fails.

The error is a communication error with openbao:

 Put "/v1/auth/kubernetes/login": unsupported protocol scheme ""

The priority of this issue is classified "medium" because these two crds are used by the vault-oidc unit enabling SSO only for the internal vault and, so, the risk induced by skipping TLS verification in tis case is acceptable.
