[FIX] Tiki API: Fix tiki tracker item endpoint response format to Align with previous version
Context of the MR:
After fixing the Item not found (404)
issue related to the update operation of tracker items through the Tiki API endpoint: /trackers/{trackerId}/items/{itemId}
in the MR !4614 (merged), It was reported that the response has too much information and is a bit different from before. So, this MR is making sure the response goes back to how it was before, maintaining consistency.
