Test fix - GraphExploreResponse HLRC xContent ordering was unreliable(#34473)

xContent ordering is unreliable when derived from map insertions but the parsed objects’ .equals() methods have the sort logic required to prove connections and vertices are correct. Disabled the xContent equivalence checks. 

Closes #33686
