[Corn Flakes] Python fix flaky test: ensure generate_random_even_number returns even numbers in range

[Copilot]

tests.test_random_math_operations_pyunit.TestGenerateRandomEvenNumber.test_even_number_is_even was persistently flaky because generate_random_even_number() could emit odd and out-of-range values (e.g., 101). This change removes that nondeterministic flaw so Python even-number generation is consistently valid.

• Problem scope

  • Python RandomMathOperations.generate_random_even_number() introduced intermittent invalid outputs, driving flaky failures in both pyunit and pytest even-number assertions.

• Behavioral change

  • generate_random_even_number() now always returns from randrange(0, 101, 2).
  • Removed the conditional mutation path that could turn valid even outputs into odd/out-of-range values.

• Test/docs alignment

  • Updated Python even-number test class docstrings to reflect reliable behavior (no longer described as intentionally flaky).

def generate_random_even_number(self) -> int:
    return self._rng.randrange(0, 101, 2)
