Redirect `groups/*id/-/details` to `/*id`

What does this MR do and why?

The groups/*id/-/details route currently renders the same template as the main group landing page. In #23466 (closed) we recently migrated the tabs on that page from HAML/jQuery to Vue (behind the group_overview_tabs_vue feature flag). The old tabs implementation updated the URL on groups/*id/-/details to /*id with JavaScript so then when you refresh the page you actually hit the main group landing page. The new Vue tabs doesn't do this and instead only controls the /-/<active tab> part of the URL. This causes issues because when you switch tabs the URL is not correct and then if you refresh you get a 404. To fix this bug, this MR redirects groups/*id/-/details to /*id at the controller level. I searched the codebase and couldn't find any references to a link or button that directly links to the /-/details route, so I am guessing it is an old route.
