class_docstr: Label unification for a label question
  
  Args:
      question (Union[LabelQuestion, MultiLabelQuestion]): label question
      strategy (Union[str, LabelQuestionStrategy, MultiLabelQuestionStrategy]): unification strategy. Defaults to "majority".
          majority (str): the majority value of the labels
          majority_weighted (str): the majority value of the labels, weighted by annotator's confidence
          disagreement (str): preserve the natural disagreement between annotators
  
  Examples:
      >>> from argilla import LabelQuestion, LabelQuestionStrategy, LabelQuestionUnification
      >>> LabelQuestionUnification(question=LabelQuestion(...), strategy="majority")
      >>> # or use a LabelQuestionStrategy
      >>> LabelQuestionUnification(question=LabelQuestion(...), strategy=LabelQuestionStrategy.MAJORITY)
