Pull Request Overview

This PR corrects a field naming issue in the GroupsTeam model by renaming the User field to Team, which better reflects the actual data structure representing a team entity rather than a user. All associated test cases have been updated to reflect this change.

• Renamed User field to Team in the GroupsTeam struct
• Updated all test mock JSON responses to use "team" instead of "user"
• Updated all test assertions to reference .Team instead of .User
