"Custom Field" data for Navigation Menu is not included, while fetching it from 'Navigation Menus Headless API'

Issue

• When trying to fetch the details of the "Navigation Menus" via the 'getNavigationMenu' Headless API, the 'Custom Field' data is not included in it.

• Steps to reproduce:
  1. Navigate to Control Panel > Configuration > Custom Fields > 'Site Navigation Menu Item' > Create a field using the text field.
  2. Navigate to Site Builder > Navigation Menu > click on the '+' button > select 'Page' (any page) and fill in the 'Custom Field' value which appears on the right side and saves it.
  3. Open the new browser's tab, hit the 'localhost:8080/o/api' > NavigationMenu > GET /v1.0/navigation-menus//{navigationMenuId} > enter the 'navigationMenuId' (it can be seen from the URL like 'siteNavigationMenuId=34026')
  4. Click on the 'Execute' button, after that, in the 'Response Body', all details are available except 'Custom Field'.

Observed behavior: After fetching the data from getNavigationMenu API, the 'Custom Fields' data is not visible.
Expected behavior: After fetching the data from getNavigationMenu API, the 'Custom Fields' should be visible.
