Enhance filtering for admin and group runner views

## Description This issue includes enhancements to the Runners Admin table view filtering that came from the [UX Scorecard recommendations](https://gitlab.com/gitlab-org/gitlab-design/-/issues/1673). This should follow up the [MVC design](https://gitlab.com/gitlab-org/gitlab/-/issues/299509) for the new Admin table view.
