Issue Summary

When space is moved to trash, it doesn't trigger `page_trashed` and `blog_trashed` events for pages and blogs that the space contains. Only `space_soft_deleted` webhook event is generated.
Currently, `page_trashed` and `blog_trashed` events are only generated when a page or blog is purged from a spaces content trash.

In comparison, when a space is deleted it triggers `space_removed` as well as `page_removed` and `blog_removed` webhook events. So, when a space is trashed webhook events should fire similarly.

Steps to Reproduce

1. Register the following webhooks with a connect app

      "webhooks": [
         {
           "event": "space_soft_deleted",
           "url": "/api/webhook"
         },
         {
           "event": "blog_trashed",
           "url": "/api/webhook"
         },
         {
           "event": "page_trashed",
           "url": "/api/webhook"
         },
         {
           "event": "space_removed",
           "url": "/api/webhook"
         },
         {
           "event": "blog_removed",
           "url": "/api/webhook"
         },
         {
           "event": "page_removed",
           "url": "/api/webhook"
         }
       ]
   

2. Send a space to trash that contains blogs and pages.

Expected Results

`space_soft_deleted` event should be generated and `page_trashed` and `blog_trashed` events should also generate.

Actual Results

Only `space_soft_deleted` webhook event is generated.

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
