Missing mongodb field "lastPublishedAt" for parked pages.

## To Reproduce

Step by step instructions to reproduce the behavior:

> 1. Create parked page in page module options for example:
```
park: [
{
parkedId: 'blogParkedId',
slug: '/blog',
title: 'Blog',
type: 'default-page',
},
]
```
> 2. Run npm run dev
> 3. Check mongodb aposDocs collection and find Blog page in published version, there is no lastPublishedAt field.


> 4. Then you can create some page and try to move this page as child of parked page. This throw a forbidden error.

>5. Tested on newly created project by CLI.

## Expected behavior
> A parked page should have DB field "lastPublishedAt",

## Describe the bug
> This causes an forbidden error (Publish parent page first), while moving another page under this parked page as child.

## Details

**Version of Node.js:**
16.13.0

**Server Operating System:**

Start by reproducing the issue in a newly created project with the shown page module park configuration, then inspect the published Blog document in the MongoDB aposDocs collection. Verify how parked pages are published and how child-page moves validate the parent. Done means the parked page has lastPublishedAt and another page can be moved beneath it without the forbidden error.
