### Problem to solve [app/assets/javascripts/pages/users/user_tabs.js](https://gitlab.com/gitlab-org/gitlab/-/blob/master/app/assets/javascripts/pages/users/user_tabs.js) has a lot of jQuery and legacy JavaScript. It is also quite hard to follow. We should migrate this to Vue to reduce technical debt. This should be completed after https://gitlab.com/gitlab-org/gitlab/-/issues/23466 since [app/assets/javascripts/pages/groups/shared/group_tabs.js](https://gitlab.com/gitlab-org/gitlab/-/blob/master/app/assets/javascripts/pages/groups/shared/group_tabs.js) relies on [app/assets/javascripts/pages/users/user_tabs.js](https://gitlab.com/gitlab-org/gitlab/-/blob/master/app/assets/javascripts/pages/users/user_tabs.js).
