docs: Strip alias from a data_type chain - this function should be
      used *after* aliases are resolved (see resolve_aliases fn):
  
      Loops through given data type chain (unwraps types), replaces
      first alias with underlying type, and then terminates.
  
      Note: Stops on encountering the first alias as it assumes
      intermediate aliases are already removed.
  
      Args:
          data_type (DataType): The target DataType chain to strip.
      Return:
          None
