Fix the issues reported by phpcs

-core: 8.x
+core_version_requirement: 8.x

core_version_requirement is not recognized from any Drupal version before Drupal 8.8. That requirement needs to be changed.

+/**
+ * @file
+ * Primary module hooks for Node Menu moodule.
+ */
+

The short description for that module is Hook implementations for the Node menus module. since Drupal core does not have primary nor secondary hooks.
moodule is a mispelled word.

+    // We need to sync menu item. Things will break if we try to do similar
+    // logicfound in menu ui submit callback, token module breaks hard.

There is a missing space between logic and found, since those are two distinct words.

 /**
- * Node form validate callback.
  * Sync main parent item with selected item from language menu.
  *
  * @param array $form
- * @param FormStateInterface $form_state
+ *   The array of form values.S.
+ * @param \Drupal\Core\Form\FormStateInterface $form_state
+ *   Form cuurent state.
  */
 function node_menus_form_node_form_validate($form, FormStateInterface $form_state) {

The documentation comment for a validation handler is different and it does not need to describe its parameters.

-  // TODO make validation work again.
-  //$form['#validate'][] = 'node_menus_form_node_type_form_validate';
+  // @todo make validation work again.

What follows @todo is a sentence: It starts with a capitalized word and it ends with a period.

Hi, I have updated the patch with the changes

+core_version_requirement: ^8 || ^9 || ^10

The minimum Drupal 8 version must be 8.8, so the first requirement needs to be ^8.8.

+ * @return array
+ *   An array that contains default values for the menu link form.

The default values for the menu link form. is sufficient.

Thanks, Updated the patch as per the suggestions.

Hi, Reviewed the patch #6, applies cleanly and resolves all the phpcs errors/warnings. And also addresses the comments mentioned at #5 .

Re-roll the patch #8 according to the latest code changes.
