      Design a data structure in Python to store integer values.
      This data structure should have the following methods:
      - add_value(value: int): Add an integer value to the data structure.
      - find_min(): Return the minimum integer value stored in the data structure.
      Example:
      >>> int_list = IntList()
      >>> int_list.add_value(5)
      >>> int_list.add_value(3)
      >>> int_list.add_value(8)
