input: Write a function to generate a triangle pattern using numbers, where each row contains numbers from 1 to the current row number. The function should have no input parameters and should directly print the pattern to the console.
  assert generate_triangle_pattern()==None
  assert print(generate_triangle_pattern())==None
output: def generate_triangle_pattern():
      for i in range(1, 6):
          for j in range(1, i + 1):
              print(j, end="")
          print()
