Fix the issues reported by phpcs

+  /**
+   * Set ReflectionClass object.
+   */

That does not describe what the method does. Then, parameters are not documented, nor is the return value.

-  public function setProtectedProperty($object, $property, $value) {
-    $reflection = new \ReflectionClass($object);
-    $reflection_property = $reflection->getProperty($property);
-    $reflection_property->setAccessible(true);
-    $reflection_property->setValue($object, $value);
-  }

What reported by PHP_CodeSniffer and shown in the issue summary does not say that method must be removed.

Please review.

+   * @param $object
+   *   The object variable.
+   * @param $property
+   *   The property variable.
+   * @param $value.
+   *   The variable of value.

Parameters are not described that way. It is not a helpful description, since it repeats the parameter names, adding variable. (Yes, a parameter is a local variable accessible from the function/method. That is how PHP works.)

+   * @return NULL
+   *   Returns Null.
+   */

If a method/function does not return anything, @return does not need to be added.

MR 50 fixes same code from MR 49 + Comments on #13.

I applied the changes from MR 50 to Drupal Version 9.5.10 and Password Policy 4.0.0 but I still get a lot of phpcs errors.
I will list just a few.
