test(crd-generator): ensure Collection properties work like List in C…

…RD generation

- Updated `ServiceSpec` to use `Collection` instead of `List` for `loadBalancerSourceRanges`.
- Modified getter and setter methods for `loadBalancerSourceRanges` to use `Collection`.
- Confirmed that CRD generation produces a field of type array when using `Collection`, ensuring compatibility and correct schema output.
