Code looks good to me, thanks for contribution @owaiskazi19

I do see other tests where we do have dependency on the same knn classes: https://github.com/opensearch-project/neural-search/blob/main/src/test/java/org/opensearch/neuralsearch/query/HybridQueryTests.java and https://github.com/opensearch-project/neural-search/blob/main/src/test/java/org/opensearch/neuralsearch/query/HybridQueryBuilderTests.java.

Did you look into those tests as well, can we do similar refactoring?

Handled HybridQueryTests. HybridQueryBuilderTests.java is tightly coupled with knn and might need another issue of it's own.
