Side menu item corresponding to the currently active page is not being visually highlighted

[MuhammedNihad]

Expected Behavior: The side menu item related to the active page should be visually distinguished from the other menu items. This could be achieved by applying a different background color, dark color would be great.

Steps to Reproduce:

1. Log in to the Django admin site.
2. Navigate to any model admin page.
3. Observe the side menu and note that the corresponding menu item is not visually highlighted.

Actual Results: The side menu item related to the active page does not stand out in any way, making it challenging for users to identify their current location within the application.

Additional Information: See the image below. The page is opened at /admin/store/sparepart/. However, the "Spare parts" side menu is not highlighted.
