Subject: [PATCH] Feature: Adds active announcements tile to v2 admin
 dashboard. (#4833)

## Because
<!-- Summarize the purpose or reasons for this PR, e.g. what problem it
solves or what benefit it provides. -->
This change adds a tile indicating active announcement count on the
admin dashboard. This will allow admins to briefly see if there have
been new announcements. Clicking on the tile will navigate the admin to
the announcements page.

## This PR
- Adds a `.active_count` scope on `announcement.rb`. It builds off of
the existing `.active` scope.
- The new scope is used in the admin/dashboardcontroller to populate
`active_announcements_count`.
- `active_announcements_count` is presented in the view as another tile
similar to the unresolved flags tile.
- The `announcement` model spec is updated to test for this new scope.


## Issue
Closes #4619
