Add test for long and complex crd

[mloiseleur]

Another attempt to try to reproduce fluxcd/flux2#4646

[stefanprodan]

@mloiseleur the YAML is invalid

 ServiceAccount \"capa-controller-manager\" is invalid: metadata.annotations: Invalid value: \"${AWS_CONTROLLER_IAM_ROLE/#arn/eks.amazonaws.com/role-arn\": a qualified name must consist of alphanumeric characters, '-', '_' or '.', and must start and end with an alphanumeric character (e.g. 'MyName',  or 'my.name',  or '123-abc', regex used for validation is '([A-Za-z0-9][-A-Za-z0-9_.]*)?[A-Za-z0-9]') with an optional DNS subdomain prefix and '/' (e.g. 'example.com/MyName')

Please remove all things from the YAML file which are not CRDs
