Original prompt

This section details on the original issue you should resolve

<issue_title>Add Scheduler module to Quickstart for publishing and expiring (unpublishing) content</issue_title>
<issue_description>## Motivation

Quickstart does not currently provide a standard way to schedule content publication or unpublication. Users that need this functionality must rely on manual publishing, custom solutions, or site-specific module installs, which leads to inconsistent behavior and added maintenance.

Scheduled publishing is a common need across campus sites, and the lack of a supported solution results in duplicated effort.

Proposed Resolution

Add the Drupal contrib module Scheduler to Quickstart as an optional, supported feature. Scheduler allows content to be published and unpublished automatically at specified dates and times, while remaining permission-based and configurable per content type.

Describe alternatives you've considered

• Manual publishing at a specific time
• Custom rules/bespoke logic
• Installing Scheduler on individual sites

These approaches are less reliable and increase maintenance and support overhead compared to a shared core solution.

Roles and Permissions considerations

• Anonymous user: No impact
• Authenticated user: Not applicable
• Content editor: Can schedule publish/unpublish dates for time-sensitive content
• Content administrator: Can schedule publish/unpublish dates for time-sensitive content, and manages permissions if also User administrator
• Administrator: Full control over configuration, access and implementation

Additional context / Use case example

• This issue is a prerequisite for deprecating the existing field_az_expiration_date on the az_news content type.
• Scheduler is a long-standing, well-maintained contrib module that provides scheduled publishing and unpublishing functionality not available in Drupal core, and is commonly used where timed content release is required.
• Including Scheduler in Quickstart would reduce the need for custom solutions and one-off requests, aligning with Quickstart’s goal of providing shared, reusable functionality.
• The module can remain optional and permission-based, minimizing risk while enabling a commonly requested capability.
