Fix checkbox UL rendering issue

Fixes laurent22#11059

Fix the markdown parser to correctly render normal UL and Checkbox UL separately.

* **Assets/TinyMCE/JoplinLists/src/main/ts/core/NormalizeLists.ts**
  - Add `isCheckboxList` function to check if a list is a checkbox list.
  - Modify `normalizeLists` to handle checkbox lists separately.

* **Assets/TinyMCE/JoplinLists/src/main/ts/listModel/JoplinListUtil.ts**
  - Correct typo in `findContainerListTypeFromElement` function.
  - Ensure `findContainerListTypeFromElement` correctly identifies checkbox lists.

* **Assets/TinyMCE/JoplinLists/src/main/ts/listModel/ParseLists.ts**
  - Import `isCheckboxListItem` from `JoplinListUtil`.
  - Update `parseLists` to handle checkbox lists separately and set the correct list type.
