docs: Get underlying dependencies that are shared between distributions.
  
      If more than two distributions are provided, any pair-wise dependency
      between any two distributions are included, implying that an empty set is
      returned if and only if the distributions are i.i.d.
  
      Args:
          distributions:
              Distributions to check for dependencies.
  
      Returns:
          dependencies (List[Dist]):
              Distributions dependency shared at least between at least one pair
              from ``distributions``.
  
      Examples:
          >>> dist1 = chaospy.Uniform(1, 2)
          >>> dist2 = chaospy.Uniform(1, 2) * dist1
          >>> dist3 = chaospy.Uniform(3, 5)
          >>> print(chaospy.get_dependencies(dist1, dist2))
          [uniform(), Mul(uniform(), 0.5), Uniform(lower=1, upper=2)]
          >>> print(chaospy.get_dependencies(dist1, dist3))
          []
          >>> print(chaospy.get_dependencies(dist2, dist3))
          []
          >>> print(chaospy.get_dependencies(dist1, dist2, dist3))
          [uniform(), Mul(uniform(), 0.5), Uniform(lower=1, upper=2)]
