Prevent Pre-Publish Panel from Displaying Incorrect Information After Navigating away

[sarthaknagoshe2002]

Fixes: #64913

What?

This PR addresses a bug highlighted in #64913 where the pre-publish panel displays incorrect or broken information when switching to edit a template part. Specifically, if you open the pre-publish checks and immediately switch to edit a template part, the panel continues to show details about the template part, instead of closing or updating appropriately.

Why?

This fix improves the user experience by preventing confusion caused by incorrect information in the pre-publish panel. It ensures the behavior aligns with expectations, where the pre-publish is closed when navigating away.

How?

The issue is resolved by ensuring that when the user navigates away from editing the page, the pre-publish panel is closed. This change ensures that the publish flow is not interrupted and the pre-publish checks are only shown for the current page or post, not the template part.

Testing Instructions

1. Open a draft page in the editor
2. Ensure pre-publish checks are enabled
3. Click on publish to open the pre-publish panel
4. Select the header then click 'Edit' in the block toolbar
5. Now the pre-publish panel closes when navigating away
