Change "Archived" tab title on group overview page to "Inactive"

Problem

As per discussion in #25368 (comment 1703162080) - the archived tab on the group overview page currently includes projects that are archived and those that are pending deletion.

Proposal

To make the tab content more clear from the title, and to align with the proposal in Modernize sorting and filtering in Your Work > ... (#25368 - closed), we should update the tab title from Archived projects to Inactive. The empty state should display No inactive projects.

Implementation guide

1. Change app/assets/javascripts/groups/components/overview_tabs.vue#L204 to Inactive
2. Change https://gitlab.com/gitlab-org/gitlab/-/blob/master/app/assets/javascripts/groups/components/empty_states/archived_projects_empty_state.vue#L9 to No inactive projects.
3. It doesn't look like we have documentation about this tab. We should add some documentation about the Inactive tab to https://docs.gitlab.com/ee/user/project/working_with_projects.html. We can ping @lciutacu for technical writer review.
4. Change config/routes/group.rb#L26 route to inactive.
5. Add redirect to archived based on https://guides.rubyonrails.org/routing.html#redirection
6. Change app/assets/javascripts/groups/init_overview_tabs.js#L17 to inactive
7. Change app/assets/javascripts/groups/constants.js#L7 to inactive
8. Find and replace ACTIVE_TAB_ARCHIVED -> ACTIVE_TAB_INACTIVE
