input: Write a python function to generate a list of n unique random numbers between 1 and 10.
  assert len(generate_random_numbers(5)) == 5
  assert all(1 <= num <= 10 for num in generate_random_numbers(5))
  assert len(set(generate_random_numbers(5))) == 5
output: import random
  
  def generate_random_numbers(n):
      return random.sample(range(1, 11), n)
