Provide Evaluations in same order as they where submitted

[flyinfish]

as discussed https://github.com/quarkiverse/quarkus-langchain4j/pull/1209/files#r1908303398

this change provides

• stable order for scorer.evaluate(...)
• generic typed EvaluationReport<T> report = scorer.evaluate(...);
  @cescoffier or is it by purpose that EvaluationReport was not generically typed? i stumbled upon it having some compile-issues when sorting
