Add router to group overview tabs

What does this MR do and why?

Related to #23466 (closed)

Follow-up to !95850 (merged)

In !95850 (merged) we introduced the group_overview_tabs_vue feature flag to start converting the group overview tabs from HAML/jQuery/Vue to fully Vue. This MR builds on the previous MR and adds Vue router so the URL changes when you change tabs.

Future MRs

1. Add search and sort functionality
2. Default enable feature flag
