[SPARK-52251] Support generating both v1alpha1 and v1beta1 from CRD generator
### What changes were proposed in this pull request? This PR adds support to generate SparkApplication and SparkCluster CRD yaml with both v1alpha1 and v1beta1 version, with storage set to v1beta1. ### Why are the changes needed? With this patch, our gradle task would be able to generate yaml that matches latest changes in CRD POJO, and save us from maintaining the yaml files for new version. The similar pattern can be used when we promote to future (v1/v2 ...) versions. We may keep the previous version POJO in separate package, leaving them as a reference, and specify the storage version only to the latest. No ### Does this PR introduce _any_ user-facing change? No ### How was this patch tested? CIs. Also, validated the generated yaml includes both versions. ### Was this patch authored or co-authored using generative AI tooling? No
